AR257 carbon dioxide, humidity and temperature transducer

Carbon dioxide, humidity and temperature transducer, optionally LCD display, 0/4 ÷ 20mA current output, 0/2 ÷ 10V voltage output or digital RS485, IP65 wall housing.

Product Description

  • high-quality digital sensor for carbon dioxide (CO2) and humidity (RH) and temperature (T) in closed rooms to improve the comfort and well-being of people staying there
  • application in many fields and applications (for industrial, office and residential environments, inside buildings, e.g. HVAC installations, storage, production, transport, food sector, pharmacy, medicine, gardening, laboratories and others)
  • probe integrated with the housing or external
  • current output 0/4 ÷ 20 mA, voltage 0/2 ÷ 10 V or RS485 interface
  • programmable ranges of measured value processing
  • LCD display with a keyboard (optional) allowing configuration of parameters
  • configuration of parameters from the keyboard, through the RS485 or PRG port (AR956 or AR955 programmer) and the free ARsoft-CFG computer program enabling quick setting and copying of all configuration parameters
  • high stability of measurements
  • IP65 degree of protection provided by the housing that increases the reliability of work due to high resistance against water and dust penetration and surface condensation of water vapor inside the device, IP20 probe
  • calculating the dew / frost point [°C], absolute humidity [g/m3] (calculations for atmospheric pressure 1013 hPa) with the possibility of combining the calculated values ​​with the analogue output
