formaldehyde, TVOC, and dust should be measured to make sure they do not exceed the maximum level of concentration. Use of low emission materials in building is recommended to reduce the level of TVOC or formaldehyde. Indoor air quality testing should be performed by a Certified Industrial Hygienist from UF EHS department.

Unlike our Radon, Temperature, Humidity, and Pressure Sensors, the sensor measuring VOC and CO2 equivalent is a relative sensor. A relative sensor measures changes in levels with very high precision but does not report absolute levels. The builtin logic performs periodic selfleveling to compensate for any long term sensor drift or sensor aging.
This study evaluated the emissions of specific indoor sources usually present in Portuguese dwellings in order to understand their impact on the indoor air quality. With this aim, three typical activities were studied including home heating using two types of fireplaces (open and closed) and biofuels (pinewood and briquettes), cooking styles (frying and boiling) in different types of kitchen ...

Online Gas Chromatograph Principle. The most common type of chromatography used in continuous process analysis is the gas chromatograph (abbreviated “GC”), so named because the mobile phase is a gas (or a vapor ( Note 1 ) rather than a liquid. In a GC, the sample to be analyzed is injected at the head of a very long and very narrow tube ...
