Description: Digital humidity/temperature controller Model 7210 gives a direct and accurate display of humidity and temperature based on the classical but accurate dry/wet temperature sensing technique. There are 4 control relay outputs for switching of humidifier, dehumidifier, heater and cooler logics. Humidity measurement ranges from 0-99% whereas temperature display is from 0-99.9°C. The sensors are sealed platinum PT100 sensors in SS making them immune to atmospheric gases. This microcontroller- based model does away with the need of any look-up table to calculate the relative humidity. A sturdy sensor body has an in-built water reservoir with facility to connect a water-drip to ensure the wick never dries up making it ideal for remote locations requiring high accuracy up to ±2% ± I least significant digit for humidity and ± 0.2°C ± I least significant digit for temperature. Optional RS232 output can be connected to loggers/recorders. With membrane type front panel switches and powder coated metallic housing, it is a rugged solution for industrial use.
