Aeroqual Hydrogen Sulfide (H2S) Sensor Head 0-10 ppm (EHS)
Aeroqual Hydrogen Sulfide (H2S) Sensor Head 0-10 ppm (EHS)
Hydrogen Sulfide (H2S) Head uses Gas Sensitive Electrochemical (GSE) technology to detect H2S gas from 0-10 ppm at 0.01 ppm resolution with <±0.05 ppm accuracy (in concentrations from 0 - 0.5 ppm) or <± 10% accuracy (in concentrations from 0.5 -10 ppm).

Description / Aeroqual Hydrogen Sulfide (H2S) Sensor Head 0-10 ppm (EHS)
Hydrogen Sulfide (H2S) Head uses Gas Sensitive Electrochemical (GSE) technology to detect H2S gas from 0-10 ppm at 0.01 ppm resolution with <±0.05 ppm accuracy (in concentrations from 0 - 0.5 ppm) or <± 10% accuracy (in concentrations from 0.5 -10 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 at a 60 second response time.

Calibration:
This sensor is a Non-dispersive Infra-red (NDIR) sensor. The Aeroqual AQ EHS sensor has a detection range of 0-10 ppm, so the calibration gas you use must fall within this range. Refer to the table below for our recommended calibration gas options.
Sensor Type:
There are two types of Aeroqual sensors, type 1 and type 2.
The type 1 is used with the S-200, S-300, S-500, Ranger and S-900 monitors.
The type 2 is calibrated specifically with fittings on the end allowing it to be used with the ENC enclosure and in the S930
