Humidistats are designed for two-state control of e.g. heating, ventilation, humidifier, dehumidifier, etc.
Transmitter is equipped with two relay outputs for alarm indication or control of external devices. Each relay can be assigned to any measured or computed value. For each relay setting of delay, hysteresis, audible alarm is enabled.
Measured temperature and relative humidity is recalculated to other humidity interpretations - dew point temperature, absolute humidity, specific humidity, mixing ratio or specific enthalpy.
Parameters are easy adjustable from regulator keyboard or from the computer. Large dual line LCD for simultaneous display of temperature, relative humidity or other calculated humidity interpretation is an advantage.
State-of-the-art capacitive polymer sensor ensures excellent calibration long term stability, inertia against water and condensation. Transmitter is designed for use in non-aggressive environment.
Models H3061P and H3021P are designed for compressed air measurement up to 25 bars.

To set regulator easily by the user from the PC program buying of SP003 cable is necessary - see Optional accessory.
Free configuration program TSensor for regulator adjustment is ready to download anytime.
It is also enabled to adjust regulator from the instrument keyboard.
If different adjustment of relay outputs is required, please specify required output values (RH, T, Tdp, ..) in the order. Adjustment is free of charge.

Any measured value - temperature, relative humidity, dew point temperature, absolute humidity, specific humidity, mixing ratio or specific enthalpy can be assigned to each output of dual output transmitters. Also identical value can be assigned to both outputs.

* Relative humidity at temperature over +85°C is limited in accordance with the graph. Near plastic case with electronics and probe cable maximum temperature is +80°C.
