2004-10-01· The best approach to VOC measurement in many cases is to use a multi-sensor instrument capable of measuring all of the atmospheric hazards that may be present. Having a single instrument equipped ...
This paper reports a volatile organic compound (VOC) sensor based on olfactory receptors that were reconstituted into a lipid bilayer and used in a specifically designed gas flow system for rapid parts per billion (ppb)–level detection. This VOC sensor achieves both rapid detection and high detection probability because of its gas flow system and array design. Specifically, the gas flow ...
BAPI’s VOC sensor contains an adaptive, self adjusting, Volatile Organic Compound (VOC) sensor element that provides a CO2 equivalent control signal output. When incorporated into a control strategy based on ASHRAE’s Demand Control Ventilation algorithm, ventilation using this sensor will achieve true indoor air quality and not just CO2 dilution.

PID sensors have a specified level of energy, also measured in eV, and in general, any compound with an IP value less than the sensor’s eV rating will be ionized and detected. For example, with a eV VOC sensor, the presence of benzene (IP = eV) will be detected, whereas molecules water vapor (IP = eV) will not.

The VOC sensor directly measures ambient concentrations of a broad range of “reducing gases” associated with bad air quality. Examples are: alcohols, aldehydes, ketones, organic acids, amines, organic chloramines, aliphatic and aromatic hydrocarbons. These gases all burn and cause the VOC sensor ppm output to increase.

Aeroqual VOC Sensors Aeroqual offers two types of VOC measurement sensors; Photoionization Detector (PID), and Gas Sensitive Semiconductor (GSS). Both sensor types are non-selective which means they can be used for measuring a wide variety of VOCs.
Unlike a CO2 sensor, a VOC sensor cannot indicate the rate of ventilation needed, only the level of VOCs in the air. It also cannot necessarily indicate whether safe or harmful concentrations of VOC contaminants are present. It can indicate a general change in the concentration of contaminants.
Additionally, fixed multi gas detector or LEL Sensors are suitable for the detect concentration of poisonous and harmful, inflammable and explosive gas in the air. Moreover, It is widely used in metallurgy, Garbage Dump, Leather Factory, power plant and chemical industry. In addition, it is also used in coal mines, oil mines, on farms, warehouse, tunnels, underground pipeline and other places ...
