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 -148
to +68°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.
