Gastec GHS-8AT-EX Hydrogen Sulphide Data Logger
Gastec GHS-8AT-EX Hydrogen Sulphide Data Logger H2S continuous monitoring is simple, convenient and reliable.
If corrosive hydrogen sulphide is generated in the sewer system, it makes rust in the sewer and generates odours from underground.
In the worst case, the H2S gas greatly damages buildings and facilities.
The GHS-8AT-EX data logger makes it possible for continuous monitoring in the sewer system.
Continuous monitoring is provided to watch the sewer system, corrosion of sewage pipelines and generation source of offensive odours.
To calibrate the GHS-8AT-EX, use the dedicated calibration hydrogen sulphide generating kit to generate gas and then perform calibration. When using the GHS-8AT-EX, it is also necessary to use the applicable CK-11-E series calibration hydrogen sulphide generating kit.
*We also have a kit which does not include the GV-100 gas sampling unit.
