PID / VOC Monitors: Questions, Myths and their Proper Use

2018-04-16· 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 …

VOC Sensors and Monitors - Volatile Organic Compounds

PID type VOC sensors are more resilient and can detect a wider variety of VOCs. Learn more > Measuring targeted VOCs. Targeted VOC measurements are useful in controlled environments ( labs, research) where the target compound is used and process control or health and safety risks are required. To measure a targeted VOC, a known correction factor is applied to calculate the relative value ...

PID SENSORS FOR VOC TECHNICAL DATA LIFESPAN …

PID sensors can be installed in both portable and stationary madur devices. Currently, our devices use Alphasense PID-A1 Photoionization detector. madur proposes two stock ranges of VOC detection - 100 ppm and 1000 ppm, both with resolution of 1 ppm. However, as the PID-A1 has a linear dynamic range from 100-ppb to 6,000-ppm (Isobutylene), it can be calibrated for a different range to suit our ...

PHOTO-IONIZATION DETECTION (PID) TECHNOLOGY

PID lamps can be created with a number of gasses, each of which has different photon energy. TSI’s PID probes use Krypton gas, with photon energy of eV. While the intensity of PID lamps may change over time, or from lamp to lamp, affecting the absolute VOC measurement, PID sensors with a given lamp type will have the same photon energy.
