Aeroqual Hydrogen Sulfide (H2S) Sensor Head 0-100 ppm (EHT)
Aeroqual Hydrogen Sulfide (H2S) Sensor Head 0-100 ppm (EHT)
Hydrogen Sulfide (H2S) Head uses Gas Sensitive Electrochemical (GSE) technology to detect H2S gas from 0-100 ppm at 0.1 ppm resolution with <±0.1 ppm accuracy (in concentrations from 0 - 5 ppm) or <± 10% accuracy (in concentrations from 5 -100 ppm.)

Description / Aeroqual Hydrogen Sulfide (H2S) Sensor Head 0-100 ppm (EHT)
Hydrogen Sulfide (H2S) Head uses Gas Sensitive Electrochemical (GSE) technology to detect H2S gas from 0-100 ppm at 0.1 ppm resolution with <±0.1 ppm accuracy (in concentrations from 0 - 5 ppm) or <± 10% accuracy (in concentrations from 5 -100 ppm)
This head uses an active sensor technology with an internal fan to pull air across the GSE sensor at a specific flow rate for accurate gas detection. The fan pulls a stream of air past the sensor every 30 seconds providing a new reading of H2S levels and a 60-second response time.
