2020-01-15· The high-range sensor (PN# VP) detects VOCs in the range of 0 – 500 ppm. When both the low-range and high-range VOC sensors are exposed to similar high VOC levels simultaneously, several things jump out at you. The first thing you’ll notice as the VOC level readouts climb is that the high-level sensor updates more often. The high-range ...

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.
The high sensitivity VOC gas sensor, is the highest sensitivity VOC gas sensor for sub PPB level detection. Product Details. eV VOC Gas Sensor. Range: 0 to >100 ppm. Minimum detection limit: 100 ppb. eV lamp. The eV VOC gas sensor lamp extends the range of detectable compounds, only available from ION Science. Product Details . Sensor Comparison Table.

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 ...
