Buy Audiometers in Nigeria.

Which audiometers can I buy in Nigeria through Franance?

There are three currently assigned catalogue products, and they serve different levels of work:

- MAICO MA 25: a portable air-conduction screening audiometer. Its manufacturer lists eleven frequencies from 125 Hz to 8 kHz, hearing levels from −10 to 100 dB HL, pure and warble tones, and battery, power-supply or USB-to-PC operation. The MA 25e is a distinct extended version with automated Hughson-Westlake testing, talk-forward and optional software; verify whether the offer is MA 25 or MA 25e.
- MAICO MA 28: a portable screening audiometer with air conduction and optional bone conduction. MAICO lists an automated Hughson-Westlake test and internal storage for up to 500 patients/3,500 tests; printer, bone-conduction components and Sessions software are options whose inclusion must be confirmed.
- Interacoustics AD226: a portable hybrid diagnostic audiometer for routine air- and bone-conduction threshold audiometry. Interacoustics offers basic and extended test batteries; extended functions require the relevant license. It can be used as a standalone device or integrated with a PC through optional Diagnostic Suite software.

These are model-level distinctions based on manufacturer information. The exact transducers, licences, accessories, regional electrical version and supplied package should appear on the quotation. Open each exact model filter to review its catalogue entry, then confirm the configuration with Franance.

How do the MA 25, MA 28 and AD226 differ?

The MA 25 is the simplest of the listed options when the approved workflow is air-conduction screening. Its product page describes 11 test frequencies and pure or warble-tone stimuli, with pulsed or continuous presentation. Do not assume that the MA 25 includes bone conduction or the automated functions described for the MA 25e variant.

The MA 28 adds a portable enclosure and supports air conduction, with bone conduction available as an option. MAICO lists an automatic Hughson-Westlake test, an internal patient/test database and options for a thermal printer and PC software. Ask which transducers and functions are included in the exact quoted MA 28 package.

The AD226 is identified by Interacoustics as a portable hybrid diagnostic audiometer. Its basic battery includes air and bone conduction and selected tests; an extended AD226e battery adds further tests such as Békésy, Langenbeck and SISI according to the manufacturer. The Franance record is for AD226, not a separately configured AD226e line item, so request written confirmation of the licence level and accessories. The manufacturer also describes patient storage and optional AA battery operation.

Avoid comparing only by the word “portable.” First decide whether the clinic needs air-conduction screening, air and optional bone conduction, or a diagnostic test set with specified licensed functions. Then compare transducers, patient-data workflow, power options and the environment in which testing will occur.

What is air-conduction screening and when is bone conduction needed?

Air-conduction testing presents tones through headphones or another compatible air transducer. It can support the screening workflow specified by a service, but screening is not the same as a complete diagnostic assessment. MA 25 is specifically listed as an air-conduction screening audiometer. MA 28 supports air conduction and offers bone conduction as an option; AD226 supports routine air- and bone-conduction threshold audiometry according to Interacoustics.

Bone-conduction testing uses a compatible bone vibrator and may be included in a broader assessment protocol. It is not an accessory to assume: request the specific transducer, cable, placement accessories and masking capability required by the facility. For MA 28, the manufacturer calls bone conduction optional. For AD226, confirm the exact transducer set and any required masking or contralateral accessories in the proposed configuration.

The responsible audiologist or hearing professional should define the test protocol and decide which device and transducers meet it. A device’s supported test type does not establish that it is suitable for every patient, referral pathway or clinical decision. Follow the manufacturer’s intended use and the clinic’s approved procedures.

Which model fits a clinic, outreach team or diagnostic room?

For a service that needs basic air-conduction screening and a compact unit, MA 25 is the most focused option in this catalogue set. MAICO describes it as lightweight and portable, and the standard model can use three AA batteries, an external supply or USB power from a PC. If the team needs automated Hughson-Westlake testing or talk-forward, confirm that the quotation is for MA 25e and identify any software separately.

MA 28 may suit a portable screening workflow that calls for air conduction and a possible bone-conduction configuration. Its integrated carrying handle and accessory compartment may help with movement between rooms or outreach locations, but confirm what case and transducers ship with the quoted unit. Check the weight and transport arrangement against staff needs and the protection required during travel.

AD226 is the listed choice where the protocol calls for routine air and bone threshold testing and the facility wants a standalone instrument with optional PC integration. It can store patient records on the device and is described as portable. A diagnostic label does not remove the need for a quiet test environment, trained users, calibrated equipment and an appropriate clinical pathway.

For a multi-room or outreach service, share the number of users, room types, power availability, test battery, transducer inventory and data destination with Franance. Ask whether one unit or multiple separately configured instruments are being quoted and how accessories will be identified by part number.

What functions and licences should I specify?

Write down the test battery by name and required workflow rather than asking only for “audiometer with all functions.” For MA 25, distinguish the standard MA 25 from MA 25e and confirm whether automatic test, talk-forward, PC data transfer and software are needed. For MA 28, identify whether bone-conduction testing, masking, printer output and MAICO Sessions are part of the request. For AD226, specify basic or extended battery and name any tests or software integration the clinic requires.

Some listed functions depend on an optional licence or accessory. Interacoustics lists extended AD226e tests separately from the basic test battery. MAICO describes Sessions software, printer options and transducer configurations as additions or package-dependent features. Ask the supplier to identify the exact catalogue reference, licence state, transducers, headset, bone vibrator, response switch, cables, power supply, printer and software in the bill of materials.

Confirm that the intended computer, operating system, patient database and data-transfer method are compatible with the offered software version. Ask whether licences are perpetual or subscription-based, how many workstations are covered, what installation is included, and what file formats can be exported. These details are not established by the presence of a USB port, PC link or brand software name.

What room and acoustic conditions should I plan for?

Audiometry depends on test-room sound conditions as well as the instrument. Interacoustics’ AD226 instructions for use state that testing is intended in an extremely quiet environment according to ISO 8253-1. That model-specific instruction is a reminder to plan the room before buying; do not assume a portable unit makes a noisy office suitable for threshold testing.

Have the audiology and facilities teams assess ambient noise, room isolation, ventilation, lighting, patient access, chair position and electrical outlets. If a sound-treated booth or noise-excluding headphones are required by the protocol, state the exact booth or transducer model and compatibility needed. MAICO mentions noise-excluding cabins in connection with MA 25e talk-forward functionality, but this does not certify any room or cabin for your intended test.

Ask for the manufacturer’s current instructions and the facility’s room acceptance criteria. Identify whether site measurements, room treatment, booth installation or acoustic verification are part of the project quotation. Keep procurement of the audiometer separate from any booth or building work unless Franance’s written scope explicitly includes both.

How should I plan transducers, accessories and patient data?

The transducer is part of the measurement chain, so specify it by model and intended test. MAICO lists compatible air-conduction headphones for the MA 25 and MA 28 and bone-conduction transducers for models that support that function. Interacoustics provides AD226-compatible transducers and accessories through its current product documentation. Compatibility is model-specific; do not assume another manufacturer’s headset or a generic replacement can be substituted without confirmation.

List the needed transducers and consumables, response controls, spare cables, patient communication microphone or talk-forward feature, carrying protection and printer if relevant. Ask which parts are included, which are optional, and whether an accessory is compatible with the precise instrument and regional variant. If the clinic requires equipment shared across rooms, specify storage, identification and cleaning expectations in line with manufacturer instructions and facility policy.

The three instruments have different data workflows. MA 25 has a PC connection described by MAICO; MA 25e adds the specified result-transfer features. MA 28 has an internal database and optional Sessions software. AD226 stores patient records and can operate standalone, with PC integration through optional Diagnostic Suite. Confirm memory capacity for the offered configuration, user permissions, data export, backup and patient-record system before procurement. A product feature does not establish interoperability with a named hospital information system or database.

What calibration, training and service details should I confirm?

Request the current manufacturer instructions, serial-number documentation and any calibration or verification records supplied with the exact unit. Ask which transducers and reference values apply, what acceptance checks will be completed at handover, and how the facility should schedule ongoing calibration and maintenance under its quality system and applicable requirements. Do not infer a calibration interval or certificate from the product listing.

Confirm user training for the specified test battery, accessory setup, patient-data workflow, cleaning and routine checks. If a licence or PC software is included, clarify installation, configuration, user seats and support responsibility. For outreach use, ask about battery handling, storage and transport instructions for the quoted model.

Ask Franance to confirm the service route for the Nigerian destination, response arrangements, parts availability, warranty scope and exclusions in writing. The public catalogue and manufacturer pages do not prove a local service centre, response time, warranty duration or calibration coverage. Include these as quote requirements so the supplier can state what is available for the order.

What should a Nigerian audiometer quotation request include?

Send the intended service and exact model preference, test protocol, required air and bone conduction, test battery or licence, transducer models, masking and response accessories, data-transfer workflow, power requirements, quantity, facility address, city and state. Explain whether the unit will remain in a dedicated room or travel between clinics, and mention any booth, room assessment, computer or printer requirement.

Ask for an itemized written offer that names the exact manufacturer model and variant, all included transducers and accessories, licence level, software version, power supply, manuals, training, calibration documentation, installation scope, warranty and service terms. Request the quoted currency and price, delivery destination, lead time, taxes or logistics assumptions and exclusions. Ask Franance to confirm stock and fulfilment details for your location rather than relying on an online product page.

For a screening-only service, MA 25 may be the closest model if its air-conduction function matches the approved specification. If you require bone conduction or a broader diagnostic test battery, compare MA 28’s optional configuration with AD226’s basic or extended battery, and request the exact package details. Franance will follow up by phone or email after receiving the quotation enquiry; the catalogue does not take payment or confirm an order online. Request an audiometer quotation from Franance.
