Configured for Isolated RS232/485/422, this humidity and temperature controller suits industrial automation and process control. It has display of 4-digit, 9-segment LED, RED, GREEN and AMBER programmable colors.
The OMEGA iTH Series instruments monitor and control both temperature and relative humidity. All meters and controllers in the series are high quality, highly accurate instruments featuring OMEGA's award-winning iSeries technology, uncompromising accuracy, backed by an extended 5-year warranty. The controllers provide single output control for humidity and temperature and are easily programmed for any control or alarming requirement from simple on-off to full autotune PID control.
