How Does a TVOC Sensor Actually Work? - Kaiterra

What the sensor is actually measuring is the electrical resistance of this metal-oxide layer. This real time measurement and output of resistance is the first step in obtaining our TVOC reading. The change in resistance across the surface of the sensor is directly proportional to the change in concentration of the target gas(es). The exact ...

About TVOC and the Laser Egg+ Chemical

About TVOC and the Laser Egg+ Chemical About TVOC. Volatile organic compounds (VOCs) are carcinogenic, harmful chemicals that can be released, or off-gassed, into the air. VOC concentrations are consistently higher indoors (up to 10 times, according to the EPA) than outdoors and are found in common household products and furnishings. TVOC, or total volatile organic compounds, is a catch ...

TVOC Manual - Gastech

TVOC should be mounted in the location most likely to detect gas. • TVOC must be mounted vertically with the sensor underneath the case. This avoids dust and debris blocking the access to the detector cell. • Mount TVOC higher if detecting VOC gases that are lighter than air or lower if detecting VOC gases that are heavier than air (but never on the floor). This should maximise detection ...
