Description:
Precise measurement and control of Humidity (%RH)
and Temperature is essential in the pharma, food,
chemical and other industries. The models featured
here suits various applications of simultaneous measurement
and control of %RH and Temperature. Indicators are
available for simultaneous display of temperature
and %RH on 0.5” to 4” large displays. PID controls
are available for maintaining %RH and Temperature
in the stability chambers, Walk in chambers, dryers
etc… Eight and Sixteen channel Data loggers with suitable
sensors and transmitters are available for validation
of chambers, storage rooms etc… Small models are also
available for monitoring of %RH and Temp. in server
rooms, clean room storage, hot air driers etc… All
models are available with serial interface for communicating
with computer. 21 CFR part 11 compliant software is
also provided as per FDA regulations.
 APPLICATIONS
For BOD, Environmental/ Walk-in test chamber, HVAC
applications and for validation purpose
