Buy Tonometer in Nigeria.

Which tonometers can I buy in Nigeria through Franance?

The current catalogue includes three exact product records in the tonometer category:

- Topcon CT-80 Computerized Tonometer — Topcon describes computerized intraocular-pressure measurement using an air puff, selectable measurement ranges and auto or manual measurement modes. Its manufacturer page lists an integrated printer and RS-232C output.
- ZEISS VISUPLAN 500 Non-Contact Tonometer — ZEISS describes non-contact measurement using a soft puff of air. Its page lists an integrated thermal printer, serial output and an optional manual chinrest.
- Haag-Streit AT 900 Model BQ Applanation Tonometer — Haag-Streit describes an applanation instrument using the Goldmann principle. Model BQ is a slit-lamp-mounted configuration designated for specified Haag-Streit slit lamps, including BQ 900 and BP 900.

The category’s Topcon-filtered results, Haag-Streit-filtered results and ZEISS-filtered results keep each model attached to its manufacturer. Use the exact model name in an enquiry so the proposed item can be checked against the intended room and approved requirements. The catalogue does not imply that every model, mount, prism, consumable, table or service is included in a particular offer.

What is the difference between non-contact and applanation tonometers?

The three listed devices fall into two method families. Topcon calls the CT-80 a computerized tonometer that measures without contact using an air puff. ZEISS also identifies VISUPLAN 500 as non-contact, using an air puff. Haag-Streit identifies the AT 900 as a Goldmann-principle applanation tonometer. Its model BQ is mounted to the compatible slit-lamp microscope arm. These descriptions provide a procurement distinction: the first two are standalone non-contact instruments in their listed product families, while the AT 900 model BQ must be considered together with its slit lamp and mount.

This distinction is not a clinical recommendation. Franance’s category should not be used to decide which measurement approach is appropriate for an individual or service. An ophthalmologist, optometrist or other qualified eye-care lead should define the required method, device workflow and any local clinical protocols. Procurement staff can then match those requirements to the manufacturer’s documentation and the equipment actually offered.

The named products should not be ranked by a single headline such as “best” or “most accurate.” Their manufacturers publish different technical details and system arrangements. A non-contact feature does not establish that a model meets a particular facility’s workflow, and a contact-method instrument does not mean the necessary compatible slit lamp or accessories are included. Ask for a model-specific response rather than treating “tonometer” as a complete specification.

How do the three listed tonometer models differ?

Topcon CT-80. Topcon lists a measurement range of 0–60 mmHg with selectable 0–30 or 0–60 mmHg ranges. The page describes automatic or manual measurement modes, a monitor-screen display and display or printing of up to three measurements per eye. Its listed external output is RS-232C; Topcon also presents a built-in printer or export to an electronic medical record as connectivity possibilities. The manufacturer describes an adjustable safety stopper and alignment indications. Confirm which configuration, interface and output are present in the unit being offered; a listed interface alone does not prove compatibility with a named hospital record system.

ZEISS VISUPLAN 500. ZEISS lists a 7–60 mmHg measurement range, a 5.7-inch LCD TFT monitor and an integrated thermal printer. Results can also be exported through a serial interface according to the manufacturer. ZEISS lists 100–240 V input, 50/60 Hz frequency, dimensions of 270 × 359 × 501 mm and a weight of 10.9 kg. A manual chinrest is described as optional; its dimensions and weight differ when that option is fitted. Do not assume it is part of the offered package. Confirm paper type, printer supplies, optional chinrest, cable and data-output requirements in the quotation.

Haag-Streit AT 900 model BQ. Haag-Streit identifies the AT 900 as a Goldmann-principle applanation tonometer and lists a 0–80 mmHg measurement range across AT 900 variants. The model BQ is intended for particular slit lamps, including BQ 900 and BP 900. The manufacturer says the instrument mounts permanently on the microscope arm, has a parking position and can be moved to its working position; measurement is obtained through the right eyepiece. The AT 900 model R and T have different mounting arrangements, which is why the suffix matters. The current Franance item is model BQ, not a generic AT 900 or an unspecified model R/T.

These specifications help construct an offer comparison, but figures from different measuring principles do not by themselves show that the devices are clinically interchangeable. Confirm current product literature and the exact market variant before using specification values in a tender or purchase decision.

Which tonometer method should a facility specify?

Begin with a written functional requirement approved by the clinical team. State whether the requested method is non-contact air-puff measurement or a Goldmann-principle applanation instrument, and identify the model or compatibility requirements if the facility has already selected them. If the requirement is not yet settled, ask the clinical lead to define it before the procurement team requests comparable offers. A catalogue category is useful for discovery; it cannot replace the facility’s clinical specification.

For an air-puff device, the CT-80 and VISUPLAN 500 have different manufacturer-listed ranges, displays, output methods, operating modes and optional accessories. Compare the exact features the facility requires rather than assuming one range or interface represents the other. For an AT 900 model BQ, list the exact slit lamp in the room or quote package. Haag-Streit identifies BQ 900 and BP 900 compatibility for model BQ; compatibility with another model must be checked, not inferred from the brand name.

Have the clinical team review intended use and applicable instructions for use. Have biomedical or technical staff assess equipment configuration and site requirements, and have procurement evaluate offers against the written specification. For broader context, consult the WHO user guide for medical-device technical specifications and its medical-device procurement process resource guide. These are planning resources, not confirmation that any specific product is available or approved in Nigeria.

What compatibility, accessories and infection-control details should procurement check?

For the Haag-Streit model BQ, the first compatibility question is the slit lamp. Record the manufacturer, full model and configuration of the installed instrument. Ask the supplier to confirm that the exact AT 900 model BQ, mounting parts and measurement arrangement match that slit lamp. If procurement is quoting a combined setup, ask the offer to name both instruments and state which components are included. Do not infer compatibility with third-party models or Haag-Streit’s other tonometer configurations from a broad category label.

Prisms and other accessories must also be itemised. Haag-Streit’s tonometer information describes reusable Goldmann measuring prisms and optional single-use Tonosafe prisms. Their presence, type and quantity are not established by the AT 900 product title. Ask which exact prism or other accessory is included, which items are optional, and what the current instructions require for handling and reprocessing. Follow the device and accessory manufacturer’s instructions and the facility’s infection-prevention policy; this guide does not provide a reprocessing protocol.

For CT-80 or VISUPLAN 500, confirm any chinrest or patient-positioning accessory, printer paper, power cable, interface cable, consumables and documentation required for the offered setup. Optional accessories should be clearly marked as optional or included. Ask that replacement items be identified by manufacturer reference so later purchasing can match the unit.

Ask the supplier to provide current instructions for use, product documentation and a written list of supplied components. The facility should review applicable local requirements and the exact model’s market labeling before purchase or use. No manufacturer page reviewed here establishes Nigerian regulatory registration for the exact offered unit, and this category guide does not make that claim.

How should the tonometer fit the clinic room and data workflow?

Room planning differs across these products. ZEISS lists VISUPLAN 500 at 270 × 359 × 501 mm and 10.9 kg, with a larger footprint when the optional manual chinrest is fitted. Topcon lists CT-80 dimensions of 272 × 505 × 430–458 mm and an approximate weight of 18 kg. The AT 900 model BQ mounts on a compatible slit lamp, so the relevant space and installation review concerns the assembled instrument and the slit-lamp station, not just the tonometer attachment. Check current documents for the exact offered variants before using these measurements in a layout.

Ask the facilities team to review bench or table footprint, operator position, patient access, instrument movement, cable route, cleaning access, delivery route and installation location. Confirm the required electrical supply and connection for the actual model. Although published voltage ranges may look compatible with a site’s nominal supply, that does not confirm the plug, protection, grounding, backup supply or suitability of a room installation.

For data, Topcon lists RS-232C external output and refers to printer or EMR export options. ZEISS lists a serial interface and integrated thermal printer. Neither interface description establishes compatibility with a particular EMR, hospital information system, software version or export format. Have the facility’s IT representative identify the target system and required workflow, then request written confirmation of interface, format, cable, licence, software and configuration for the exact model. Do not assume that an available port supplies a complete integration.

For a slit-lamp-mounted AT 900, ask for the mounting and operating arrangement in the offer and include any existing slit-lamp reference. Agree who will install or verify the assembled configuration and what handover is included. A quotation should separate the instrument, mounting components, accessories and any optional technical services so facility teams can assess each line.

What should a tonometer quotation request include?

Send Franance the exact model or the written functional specification, the preferred measurement method, quantity, department, destination facility, city and state, and requested delivery timing. For the AT 900 model BQ, include the exact slit-lamp manufacturer and model and state whether the tonometer is for an existing instrument or a new package. For CT-80 or VISUPLAN 500, state the measurement-range requirement, printing or data-export needs and any optional accessory requirements.

Ask the quotation to identify the manufacturer, full model and reference, market configuration, current specification documents, items included, optional items, accessories and consumables. Include the power and data requirements, installation or commissioning request, training request and warranty or service requirements. Ask Franance to confirm price, availability, delivery and commercial terms in writing for the Nigerian destination. These details are requests for confirmation; the listing does not guarantee stock, a fixed price, a delivery date, local warranty or service coverage.

If you are comparing more than one method, request separate line items and ask the clinical lead to assess them against the approved requirement. This avoids treating an air-puff instrument and a slit-lamp-mounted applanation tonometer as identical simply because both sit under the tonometer category. Submit the Franance tonometer quotation enquiry with the model references and facility requirements. Franance follows up by phone or email; payment is not collected online through this catalogue.
