VOC Sensors and Monitors - Volatile Organic Compounds

Volatile organic compounds (VOCs) are a wide range of carbon based (organic) chemicals (compounds) found in various man-made and naturally occurring solids and liquids. They evaporate easily at ordinary room temperature which is why they are termed volatile. Why measure VOCs? Some VOCs are harmful to human health and can cause environmental damage. Exposure to high concentrations of VOCs …

VOC Sensors: Volatile Organic Compounds Sensor | GDS Corp

About Volatile Organic Compounds (VOCs) Volatile Organic Compounds, or “VOCs”, are organic chemicals that have a high vapor pressure under normal atmospheric pressures and temperatures. As a result, they have a low boiling point and readily evaporate into the atmosphere, creating potentially toxic conditions for workers. A VOC Detector measures the presence of VOCs and displays a value …
