Gas Sensor Technologies used with Tox-Box VOCs Monitor

The Mil-Ram Model Tox-Box VOCs Portable Gas Monitor uses the Photo Ionization (PID) sensor technology as follows:

Photo-Ionization PID Gas Sensor

Photo-Ionization detectors are based on the principle of ultraviolet (UV) light absorption by a gas sample to produce electrically charged particles (positively charged molecular ions and negatively charged electrons). These charged particles generate measurable electrical current at the sensor electrode grid. PID detectors provide low range detection of many gas and vapor species including highly toxic volatile organic compounds (VOCs). Selectivity is based on UV source energy and ionization potential of the target gas.
