VOC Sensors - Belimo

used as VOC sensors in heating, ventilation and air-conditioning technology. This sensor element measures the conductivity of the nanocrystalline metal oxide that is applied to a substrate. These sensors only permit the measurement of a relative gas concentra-tion. As a result, it is not possible to specify a measuring range or accuracy.

BME680 Gas Sensor Accuracy for VOC

03-11-2020· BME680 Gas Sensor Accuracy for VOC. I have a question regarding the VOC accuracy. I was looking online, it seems that there is a variable called BSEC_OUTPUT_BREATH_VOC_EQUIVALENT that will give me the concentration VOC in ppm. Assuming I am interested in measuring the concentration of ethanol (2 ppm at most), what's the accuracy …

New understanding of miniaturized VOCs …

01-03-2021· Considering that the VOC concentration in ambient air was quite low, and the upper detection limit of the sensors was significantly larger (2ppm∼30 ppm), the test concentrations of accuracy, repeatability and response time test were adjusted to ambient levels, which were 20∼1000 ppb, 100 ppb, and 150 ppb respectively, instead of 80 % full span in general.
