AR258 dust, atmospheric pressure, humidity and temperature transmitter

Dust, atmospheric pressure, 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 of suspended dust (PM), atmospheric pressure, and humidity (RH) and temperature (T) of air
  • used in many fields and applications (for industrial, office and residential environments, outside and inside buildings, e.g. HVAC installations, production, food sector, weather stations, laboratories and others)
  • probe integrated with the housing
  • 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
  • When used outdoors, additional protection of the measuring probe is required against direct contact with water
  • 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
