H2S Gas Detection for Chemical Plants
Wireless and Hardwired Hydrogen Sulfide Detection Solutions

Reliable H2S Detection System
Chemical production frequently involves hazardous substances, making safety a primary concern for plant operators. Hydrogen sulfide (H2S) is commonly found in these facilities. Due to its extreme toxicity, it is vital to carefully monitor and control H2S levels to maintain safety. Chemical producers should implement gas monitoring throughout the facility to ensure worker safety. OleumTech offers a highly scalable H2S gas detection solution, allowing operators to install H2S Transmitters in strategic areas where the gas may be present. These sensors continuously monitor the air for H2S, triggering alarms if levels exceed safe limits.
Product Solutions
HW-H2S | WT-H2S | WT-H2S-A Hydrogen Sulfide Transmitters
OleumTech H2S Gas Detection Transmitters are available in either wired or wireless and are deployed to constantly monitor air quality, generating alarms when H2S concentration levels reach user-defined setpoints. This highly scalable solution provides operators with maximum flexibility to accommodate any production plant size and layout.
