Tuff-Fet & Transmitter Non-Glass pH Electrodes TEXT SIZE: A A A    PRINT THIS PAGE   EMAIL THIS PAGE

The Tuff-Fet™ sensor is a solid state, ion selective field-effect transistor or ISFET. This technology does not require a glass membrane, making it perfect for Food-Grade Applications.

Tuff-Fet with Cap Nut
3/4 inch MPT Tuff-Fet with Transmitter
Tuff-Fet with S8 Cap
Tuff-Fet with Twist-Lock Housing
 
Durability: The Tuff-Fet™ is constructed of a rugged Ryton™ material which reduces breakage.
Speed: The Tuff-Fet™ sensor speed is 10 times faster than that of standard glass electrodes and has better repeatability and stability.
Reference: The reference can be field rebuildable or sealed with a special Solid Polymer Reference (SPR™). The SPR™ greatly enhances the sensor's performance and life especially at elevated temperatures.
Transmitter: The Tuff-Meter™ is a 2 wire, loop powered, transmitter designed for mounting directly to the sensor or remotely in a field application. Sealed in a weatherproof corrosion-resistant housing, the Tuff-Meter™ is perfect for any harsh environment.
