CSO R Type Applanation Tonometer (A900)
The F900 and A900 applanation tonometers are accessories for the SL990 slit lamp to measure ocular pressure. Due to its versatile design, they can also be combined with other manufacturers equipment. The tonometers operate using the Goldmann method, meaning that it measures the pressure required for maintaining uniform applanation of the corneal surface. Precise measurement of the small flattened surface is completed using a slit lamp at 10x magnification.
Also known as the A900.
