* High-quality digital sensor for carbon dioxide (CO2), relative humidity (RH) and temperature (T) in close rooms to improve the comfort and well-being of people staying there
* Application in many elds and applictions (for industrial, office and residential environments, inside buildings, e.g. HVAC installations, storage, production, transport, food sector, pharmacy, medicine, gardening, laboratories and others
* A probe integrated with the enclosure, external or on a stainless steel pipe
* A probe integrated with the housing or external
* Current output 0/4 ÷ 20 mA, voltage 0/2 ÷ 10 V or RS485 interface
* Programmable processing ranges for measured values
* An LCD display with a keypad (option) that enables configuration of parameters
* Configuration of parameters with the keypad, through the RS485 or PRG port (programmer AR956 or AR955) and free ARsoft-CFG software that enables quick setting and copying of all configuration parameters
* High stability of measurements
* Protection rating IP65 provided by the enclosure which improves reliability of operation thanks to high resistance to penetration of water and dust and surface condensation of steam inside of the device, an IP20 probe
* Calculating the dew / frost point [°C], absolute humidity [g/m3] (calculations for atmospheric pressure 1013hPa) with the possibility of combining the calculated values with the analogue output
