MiniPID 2 PID sensor

0-40 ppm range, 1 ppb sensitivity, 10.6 eV lamp

Designed for OEMs, we manufacture and supply more photoionisation detection (PID) sensors than any other company in the world with our sensor technology trusted by major gas detection manufacturers, globally.

Our patented Fence Electrode Technology is proven to resist humidity and contamination, giving you outstanding results when detecting volatile organic compounds (VOCs) within the most challenging environments.

MiniPID 2 is a simple plug-and-play sensor able to deliver a dynamic and dependable response to thousands of volatile organic compounds (VOCs) across many diverse applications.

The sensor is designed for both diffusive and in-line pumped sampling, delivering an exceptional response time and clear down. MiniPID 2 incorporates lamps of exceptional brightness and stability enabling detection of less volatile and less readily sensed compounds reliably, over an extended period of time.

MiniPID 2 detection ranges

PPM MiniPID 2: range 0 – 40 ppm with 1 ppb sensitivity
This PPM variant is used for wide range, part per million (ppm) measurements between 0.001 and 40 ppm (isobutylene equivalent). This sensor is configured specifically for dynamic response to VOCs at elevated concentrations allowing for greater accuracy and repeatability.
