VOC Gas Detectors


VOC (Volatile Organic Compounds) PID Detectors

A photo ionization detector (PID) measure volatile organic compounds VOC and other toxic gases in low concentration from part per billion up to 10,000 part per million or 1% by volume. A PID is a very sensitive broad spectrum monitor. All elements and chemicals can be ionized, but they differ in the amount of energy they require. The energy required to displace an electron and ionize a compound is called its Ionization Potential or IP, measured in electron volts (eV). The light energy emitted by an UV lamp is also measured in eV. If the IP of the sample gas is less than the eV output of the lamp, then the sample gas will be ionized.

VOC (volatile organic compounds) are a huge family of gases and gaseous substances, many of which are considered pollutant, toxic or carcinogenic. Because of their volatile nature, they easily spread into the atmosphere. Thus it is necessary to get protected against them with VOC detection and measurement devices such as a VOC detector.
