Haag-Streit BQ900 Tonometer

This used Haag-Streit BQ900 tonometer attachment is designed to pair with the BQ900 slit lamp platform, delivering the same trusted Goldmann applanation measurement principle that has anchored glaucoma diagnostics for decades. Built to integrate seamlessly with the BQ900 biomicroscope, this tonometer provides smooth mechanical operation and precise intraocular pressure readings that clinicians rely on for both initial diagnosis and ongoing glaucoma management. Its optical and mechanical components are engineered for long service life in busy eye care settings. The unit offered here comes from an active clinical environment and displays typical light wear from regular use, while remaining mechanically sound and fully operational. The measuring drum, prism assembly, and mounting arm are all intact and move freely, allowing for accurate applanation readings once installed on a compatible slit lamp. Practices seeking to add tonometry capability to an existing BQ900 setup, or to replace an aging unit, will appreciate the reliability this tonometer has demonstrated over its working life. As with any pre owned Goldmann style tonometer, calibration should be checked against a certified test bar before returning the unit to clinical service. This BQ900 tonometer is a solid choice for ophthalmology and optometry practices that want proven, slit lamp integrated IOP measurement at a fraction of new equipment cost.
