Colswe VOC logger measures the quantity of volatile organic compounds (VOCs) in ambient air. Measurements can be read directly via an USB connection or they can be stored in its internal flash memory for later retrieval via the USB connection.
Colswe VOC logger is ideal to monitor the air quality in residential, commercial and industrial spaces. The MEMS metal oxide sensor used in this device measures the variation of total volatile organic compounds in ambient air. The measurements are used to estimate the concentration in ppm CO2 equivalents (relative).
Colswe VOC logger detects alcohols, aldehydes, aliphatic hydro-carbons, amines, aromatic hydro-carbons (petrol vapors, etc.), carbon oxides, CH4, LPG, ketones and organic acids. Be aware that the first estimation is only available 5-6 minutes after powering on Colswe VOC logger.
The initial estimated value measured by Colswe VOC logger is 450 ppm CO2 equivalents (theoretical value for fresh air). The sensor measures relative variations of volatile organic compounds to provide an estimated ppm value, with an automatic baseline correction. The absolute value must therefore be interpreted with great care, as it is subject to drift. It is not comparable with the absolute value measured by a Colswe VOC logger but it has the advantage of including a broader range of volatile organic compounds than a simple CO2 sensor.The sensor part can be split from the main USB board and moved several meters away using ribbon cable, soldered on the designed contact pads. This may be useful to move the sensor close by to HVAC ducts.
Colswe VOC logger can be connected directly to an Ethernet network with a Colswe Hub Ethernet, to a WiFi network with Colswe Wireless SR or to a GSM network with a Colswe HUB GSM.
