Hydrogen Sulphide (H2S) Detectors
We supply fixed and portable hydrogen sulphide gas detectors to ensure comprehensive protection. Fixed systems provide 24/7 monitoring in processing facilities, pipelines, and treatment plants, while portable detectors give workers immediate warning of exposure during maintenance, confined space entry, or field operations.
Our extensive hydrogen sulphide detector range includes equipment from trusted manufacturers: BW, Crowcon, Dräger, Gas Data, GMI, Honeywell, ION Science, MSA, RAE Systems, Riken Keiki, Senko, and Uniphos.
Safeguard workers and operations with our fixed and portable hydrogen sulphide detection systems, trusted across oil, gas, water treatment, and industrial sectors.
H₂S monitoring is typically performed using electrochemical sensors with fast response times and high sensitivity down to low parts-per-million levels. Some detectors also feature data logging, multi-gas monitoring, and integration into plant-wide safety systems. Regular calibration ensures consistent accuracy and compliance with workplace safety standards.
Hydrogen sulphide (H₂S) is a highly toxic, flammable gas with a characteristic rotten egg smell, common in oil and gas, wastewater treatment, mining, and pulp and paper industries. Even at low concentrations, it can cause eye and respiratory irritation, while higher levels rapidly lead to loss of smell, unconsciousness, and can be fatal. Because H₂S is heavier than air, it often accumulates in confined spaces, increasing the risk of sudden high-exposure incidents.
