VOC Sensors and Monitors - Volatile Organic Compounds

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. To achieve this they have been calibrated against isobutylene that allows them to respond to a wide range of VOCs at varying degrees of sensitivity. Each type has a ...

A VOC Sensor Can Protect Your Health in the COVID-19 Era

Volatile Organic Compounds (VOCs) are a large group of chemicals that are commonly found in homes, offices, and other indoor spaces. Once these chemicals find their way inside, they are released or “off-gassed” into the indoor air we breathe. VOCs are generally measured as a cohesive group (Total VOCs); the Awair VOC sensor reacts to over fifty. VOCs are found in building materials ...

New Tech Tuesdays: 2 Air Quality Sensors Good for Health ...

VOC sensors can be used to detect high pollution that might occur when special equipment is being used or when potent chemicals from cleaners are released into the air. CO 2 sensors would specifically reduce ventilation during unoccupied periods, but VOC sensors might maintain ventilation rates during unoccupied periods if a significant pollutant level in the building is detected.

VOC - Duct or Rough Service VOC Sensor - BAPI

The CO2 equivalent (CO2e) units combine the benefits of VOC sensors and the common application of CO2 sensors into one unit. It provides a VOC reading that correlates to a typical indoor CO2 level of 0 to 2,000 ppm. This allows the sensor’s output to be used for ASHRAE’s CO2-based VRP ventilation schedule. CO2e units come with 3 VOC level status LEDs on the face of the unit. The total VOC ...
