This Sulfer Dioxide (SO2) Sensor Head uses Gas Sensitive Electrochemical (GSE) technology to detect Sulfer Dioxide 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 sensor 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 60 seconds providing a new reading of SO2 levels and a 60 second response time for the sensor.

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

All sensors require a yearly calibration to ensure your gas measurements are accurate and performing within manufacturer standards. This page is desiccated to the individual manufacturers we represent and their specific calibration procedures.
