AR259 TVOC, humidity and temperature transmitter

Product Description

• measurement of the concentration of harmful volatile organic compounds (TVOC) contained in the air in enclosed spaces to enable the comfort of people staying there to be improved
• configurable architecture enabling 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
• high quality, digital TVOC sensors, relative humidity and temperature, reputable company Sensirion
• 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
• temperature compensation of humidity and high long-term stability of measurements
• 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
• 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
