VOC Room Sensor Installation and Operation Instructions

Humans exhale Volatile Organic Compounds (VOCs) as well as CO 2. The BAPI sensor is able to measure these VOCs, therefore it is as good an indicator of space occupancy as a CO 2 sensor. The BAPI Sensor is different from other VOC sensors because it has been optimized for Demand Controlled Ventilation (DCV). Using a calibration algorithm, the sensor value is converted to an output with a high ...

VOC – Gas Sensing Blog

2021-04-08· In this video we demonstrate the use of the Aeroqual Series 500 in a real-world demonstration of VOC (Volatile Organic Compounds) emitted as gases into the air around a freshly laid epoxy floor. The demonstration begins with exterior readings that show very minimal VOC’s. As the high-range sensor that accurately reads 0-500 ppm (parts per million) is moved closer to the interior room …

Volatile organic compound - Wikipedia

Volatile organic compounds (VOC) are organic chemicals that have a high vapour pressure at room vapor pressure correlates with a low boiling point, which relates to the number of the sample's molecules in the surrounding air, a trait known as volatility.. VOCs are responsible for the odor of scents and perfumes as well as pollutants.

A VOC sensor was installed and the customer thought it was faulty because the output stayed at maximum no matter how much outdoor air was admitted to the building. Subsequent troubleshooting revealed that a recently installed molding machine had its exhaust vented into the building’s fresh air intake duct by mistake. Within two weeks of rerouting the exhaust, all occupant respiratory ...

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 ...
