The TriGas Monitoring System consists of up to three sensors with Ultima® X3 Technology’s digital communications with on-board LEDs and relays to provide local alarms. This TriGas system offers  interchangeable smart sensors, internal DC-powered sample-draw pump and a hydrophobic end-of-line filter that makes it  ideal for areas of wastewater treatment plants that are subject to flooding (such as wet wells).

The TriGas Monitoring System typically monitors for oxygen, hydrogen sulfide and combustible gases (methane or petroleum vapors) and is specifically designed for optimum performance within high-moisture environments. This system can also be supplied with the proper options to meet the NFPA 820 section 1.8 standards followed by the wastewater industry.
