Transmet I.S.

 Complete Dew-Point Solutions for IS Areas
Transmet I.S. is an easy to install, self-contained dew-point transmitter for the measurement of the dew point of gases, and has been specifically designed for use within hazardous areas. Housed in a stainless steel case, Transmet I.S. offers ingress protection to NEMA 4X. With a wide operating range from -150 to +70°F dew point and accuracy of up to 1.8°F dew point it is the most complete dew-point transmitter available. Transmet I.S. has a fast response speed that gives the user a continuous measurement in real time. No configuration or calibration is necessary - Transmet I.S. is delivered configured and calibrated, ready for installation and operation.
