· PID Detectors are commonly used to monitor VOC’s (Volatile Organic Compounds). Many gases and vapours fall under the VOC banner and IGD’s PID’s can monitor for over 300 Gas species. This makes a PID an ideal first responder for VOC leaks even though the PID cannot directly determine the gas type detected.
concentration if you know that there may be several VOC’s present. Note TSI PID sensors cannot measure all VOCs or gases. VOC’s that have an electronvolt potential greater than or equal (≥) to eV will give no response since they cannot be ionized by the eV lamp source. SemiVolatile Organic Compounds (SVOC) cannot be measured if the vapor pressure is too low (a few ppm at 20 ...
· PID sensors are not good at measuring explosive levels of hydrocarbons. PIDs are designed to measure ppb and ppm concentrations of organic compounds and when exposed to over 1000ppm tend to give erratic reading as due to condensation of the VOC being detected and being outside the linear range of the calibration. As such, please ignore manufactures claims of reading in to …

Description. The VOC Pro Series Gas Detector is a versatile assembly that uses a PID sensor to detect a variety of gases. Wired power (12 to 35 VDC) with 420 mA analog and RS485 Modbus outputs are standard. Magnetic switches allow for nonintrusive calibration while in the field as well as full system settings and diagnostics.
With a PID, the sample gas is exposed to deep ultraviolet light. The emitted light ionises targeted gases and they are then detected by the PID electronics and reported as a concentration (ppb or ppm). PIDs can measure Volatile Organic Compounds (VOCs) to very low concentrations.
PID sensor now available with GX6000 multigas monitor. RKI is excited to announce the availability of our latest PID sensor with an eV lamp. The PID sensor is ideal for monitoring gases such as carbon tetrachloride, acrylonitrile, chloroform, methanol, and refrigerants (R143, R132A).
This is the technology of choice for monitoring exposure to toxic levels of another group of important gases – volatile organic compounds (VOCs). The sensor includes electrodes and a lamp, which is full of a noble gas (often krypton) as a source of highenergy ultraviolet light (UV).
