Innovations In Sight



The most advanced contact lens Oxygen Polarographic Amplifier system available.

The Model 201T, Permeometer is a highly specialized instrument, primarily used by contact lens manufacturers and researchers. Designed to be used with Createch/Rehder Development Co. SSTS Polarographic Cells fitted with solid state temperature sensors, the 201T Permeometer provides a stable excitation voltage and simultaneously displays cell current and temperature on easy to read 3 1/2 digit displays.

The 201T Permeometer with Rehder SSTS cells is designed to meet the specifications of ISO 9913 and ISO18369. The 201T has a long record of reliability and is "CE" certified.

The display can be switched between two cell inputs allowing one cell to decay while the other is being read. Other cells (such as Schema Versatae) can be used but the temperature of the cell will not be displayed.
