The Haag-Streit Applanation Tonometer AT 900 model T (also known as the T900 tonometer) provides ease, flexibility, and functionality.
An extremely accurate device for the measurement of intraocular pressure between 0 to 78mmHg.
As the area of applanation is only 3.042mm the scleral rigidity does not influence readings.
The T900 attaches to the footplate of the slit lamp and is removed from the slit lamp when not in use.
The instrument can be moved between two positions on the guide plate for observation through the right or left eyepiece. The sensor arm with the measuring prism projects from the underside into the beam path of the microscope and the illumination. Tonometer will need to be removed from the slit lamp to perform exams.
Compatible with Haag-Streit BM, BI, BP, and BQ slit lamps.
Disposable tonometer prisms (such as Tonosafe™) or resusable Goldmann measuring prisms can be used with all Haag-Streit tonometers.
