Prosense PQ Series Gas Detectors
Prosense “PQ” Series fixed gas detectors have been designed and developed for the demanding conditions of the industry in order to perform continuous measurement of combustible, toxic, asphyxiate, and VOC gases in the environment.
With ATEX / IECEx, SIL2 certifications, EN 60079-29: 1 performance approval and high ingress protection class, it has proved its suitability for harsh environmental conditions.
PID, Pellistor, Electrochemical, Infrared, Semiconductor sensors employed PQ provides excellent output in LEL, ppm,ppb and VOL ranges.
To provide the best solution to evolving industry conditions and customer demands, the PQ Series is classified as PQD (With Display) and PQN (Without Display).
