MiniPID 2 PID sensor

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 – 6000 ppm with 0.1 ppm sensitivity
The PPM variant is used for wide range, part per million (ppm) measurements between 0.1 and 6000 ppm (isobutylene equivalent). This sensor is configured specifically for dynamic response to VOCs at elevated concentrations allowing for greater accuracy and repeatability.

PPB MiniPID 2: range 0 – 40 ppm will 0.001 ppm ( 1 ppb) sensitivity
The PPB variant is used for high sensitivity in the part per billion (ppb) range with a minimum detection limit of 1 ppb. The PPB sensor is optimised to deliver an exceptionally low background current allowing for optimum low-end sensitivity.

10.0 eV MiniPID 2: range 0 – 100 ppm with 0.005 ppm (5 ppb) sensitivity
The 10.0 eV variant is used for the enhanced selectivity of compounds with lower ionisation potentials. A common usage of the 10.0 eV sensor is for the determination of ambient levels of aromatic compounds.

11.7 eV MiniPID 2: range 0 to 100 ppm with 0.1 ppm (100 ppb) sensitivity 
Available from Ion Science is the 11.7 eV lamp which extends the range of detectable compounds to include chloro-carbons, CFCs, formaldehyde and chlorine amongst others.
