goldman Tonometer YZ30R
Technical Data Characteristics:
It's not only used to examine the eyes, but also measure the intraocular pressure while working under the slit lamp.
Accurate measurement ensures the total tolerrance less than ± 0.066KPa (0.5mmHg).
Directly get the intraocular pressure.
Measured intraocular pressure will not be affected by hadrness of eye.
Adjustable measuring pressure ensures the working stability and accurate measurement of tonometer in long time.
Mrasurement Range: 0-10.64 KPa
Light Ring Displacement: 1.53*2=3.06mm
Diameter of the Testing head: 7mm
Average Error: +/-70 PA
