Electronic Thickness Gauge for Contact Lense.

The Model ET-3, Electronic Thickness Gauge is a highly specialized instrument, primarily used by contact lens manufacturers and researchers. The ET-3 is designed to accurately measure the thickness of soft contact lenses and other soft materials. The instruments are built to perform with the highest degree of precision and with the highest degree of reliability possible. The instruments will stay in calibration, and will continue to function in this manner for many years.

This is the standard instrument used throughout the contact lens industry, world wide, for measuring center thickness of soft lenses.

The instrument has a range of 1000 microns and reads out in one micron increment.The ET-3 uses a precision linear transducer system to detect the position of the measuring sensor. The counterbalance and measuring sensor operating system is designed to protect the sample from accidental excessive compression.
