Temperature humidity regulators

Humidistats are designed for two-state control of e.g. heating, ventilation, humidifier, dehumidifier, etc. The unit 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. Designed for use in non-aggressive environment.

Maximum switching voltage, current, power of relay output: 50 V, 2 A, 60 VA.
Accuracy of temperature measurement: ±0.4°C from -30 to 100°C; ±0.4% from reading over 100°C.
Accuracy and measuring range of dew-point temperature: ±1,5°C at ambient temperature. T < 25°C and RH>30% range -60 to 80°C.
Accuracy and measuring range of absolute humidity: ±3g/m3 at ambient temperature T < 40°C range 0 to 400 g/m3.
Accuracy and measuring range of specific humidity: ±2g/kg at ambient temperature T < 35°C range 0 to 550 g/kg.
Accuracy and measuring range of mixing ratio: ±2g/kg at ambient temperature T < 35°C range 0 to 995 g/kg.
Accuracy and measuring range of specific enthalpy: ± 3kJ/kg at ambient temperature T < 25°C range: 0 to 95 kJ/kg.
Operating temperature range of the case with electronics: -30 to 80°C.
Operating temperature range of LCD display: readable up to operating temperature +70°C, it is recommended to switch off LCD over +70°C.
Range of temperature compensation of RH sensor: from -30 to 125°C.
Filtering ability of sensor cover: 0.025mm - filter from stainless steel mesh.
Protection: IP65 electronics with terminals, IP40 humidity and temperature sensors.
Power: 9-30 Vcc.
Dimensions of the case: 135x136x45 mm (W x H X D).
