Product Description
. . . . . Humidistat, ABS Plastic, +/-1% NIST Humidistat Control, Analog Setpoint
All HT series institutional grade relative humidity transmitters are designed to meet the rigorous needs of pharmaceutical labs, hospitals, science labs and other settings that call for precise environmental control. Internal jumpers control access to a feature that allows adjustment of the calibration offsets. The devices can also be made tamper resistant using a jumper to disable keypad programing functions. HT models are calibrated with NIST traceable calibration equipment. Analog output models feature a keypad to make adjusting humidity and temperature setpoint values easy. They transmit the setpoint values back to a control system by means of dual outputs. A slide-switch allows easy selection of output type, either 4 to 20 mA or 0 to 5 V/0 to 10 VDC signals. Dual outputs enable effortless control of both humidity and temperature in a single, compact sensor.
