Q45S hydrogen sulphide monitor uses specially developed sensor technology to enable the continuous monitoring of hydrogen sulphide in inlet and discharge air under normal condensing humidity conditions.

The system uses the Q45 electronics package with a specialised wet H2S sensor. The measurement can be taken at the inlet to the scrubber system in concentrations up to 200PPM, or at the outlet in concentrations as low as 0.5PPM.

Sensor configurations for duct insertion of flowcell use are also available.
