When used with slit lamp, it can be used to examine the eyes and measure the ocular pressure.
Accurate measurement and total tolerance is less than 0.066KPa(0.55Hg).
Directly get the ocular pressure and do not need to look up the conversion table.
The measured ocular pressure is not affected by hardness of eye.
The affected ocular volume is just 0.56 cubic millimeter.
Adjustable measuring pressure ensures the long-term stability and reliability.
