PPM VOC Gas Sensor
Range: 0 to 4000 ppm. Minimum detection limit: 100 ppb. 10.6 eV lamp. The PPM VOC gas sensor - MiniPID 2 is designed for detecting VOCs over the widest dynamic range on the market without compromising performance.
PPB VOC Gas Sensor
Range: 0 to >40 ppm. Minimum detection limit: 1 ppb. 10.6 eV lamp. The PPB VOC gas sensor - MiniPID 2 is optimised to deliver an exceptionally low background which allows for optimum low-end sensitivity.
High Sensitivity VOC Gas Sensor
Range: 0 to 3 ppm. Minimum detection limit: 0.5 ppb. 10.6 eV lamp. The high sensitivity VOC gas sensor, is the highest sensitivity VOC gas sensor for sub PPB level detection.
10.0 eV VOC Gas Sensor
Range: 0 to >100 ppm. Minimum detection limit: 5 ppb. 10.0 eV lamp. The 10.0 eV VOC gas sensor - MiniPID 2 is used for enhanced selectivity of compounds with lower ionisation energies.
