This IAQ Monitor simultaneously measures several parameters: Carbon Dioxide CO2, Carbon monoxide CO, Temperature, Relative humidity and calculates Dew Point, wet bulb temperature, absolute humidity, mixing ratio, enthalpy and atmospheric pressure. All this with the P37AB147 SICRAM probe. Also combined temperature and humidity SICRAM probes, Hot wire Air speed SICRAM probes, Vane air speed SICRAM probes and temperature SICRAM probes can be connected to the instrument.
The instrument, with proper procedure, calculates the percentage of outdoor air intake (% Outside Air) as a function of both carbon dioxide CO2 and temperature and the Ventilation Rate.
