Rotary-Dial Temperature & Humidity Controller

The OT-SH(TH)/G Temperature and Humidity Controller is equipped with a condensation sensor and a temperature sensor, enabling continuous monitoring of temperature and humidity fluctuations within the monitored environment. When the internal ambient temperature falls below a preset threshold—or when conditions indicate that condensation is imminent—the controller automatically activates a heater to raise the ambient temperature, thereby eliminating the micro-environment conducive to condensation formation. Once the conditions favoring condensation dissipate and the ambient temperature reaches the preset level, the heater automatically deactivates, and the controller reverts to its monitoring mode.
