AT 900 Model R (BM)
The Applanation Tonometer AT 900 model R can be left on your Haag-Streit slit lamp permanently. It is fastened to the microscope on a mounting base and swivelled in front of the microscope for the examination. The observation of the applanated surface is conducted monocularly – only through the left eyepiece.
This tonometer is only compatible with the BM 900 slit lamp from Haag-Streit.
