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 <±0.5 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.

This sensor head will be a direct fit onto any Series-200, Series-300, or Series-500 Aeroqual ozone monitor.  This head can be purchased as an addition to your existing monitor, or with a new base unit.  To purchase with a base unit see our Aeroqual ozone monitor page.  If you currently have an Aeroqual ozone monitor this sensor will be a direct fit for your current monitor.  The Series-200, Series-300, or Series-500 will automatically detect this as a 0-100 ppm H2S head and react accordingly.

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, 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
