Fixed Gas & Flame Detection

H2S Gas Sensors and Accessories

General Monitorsʼ hydrogen sulfide (H2S) sensors are solid state devices, designed and manufactured for long life and fast response. They are selective to H2S and remain unaffected by high concentrations of other substances like hydrogen, sulfur dioxide, and gasoline vapors, which are often present in facilities that process sour gas and crude oil. A high tolerance to a broad range of temperatures and humidity enable these sensors to operate in rugged environments, as does their capacity to withstand exposure to high H2S concentrations over short periods.

TS4000H - H2S Electrochemical Gas Detector

The TS4000H Intelligent Toxic Gas Detector continuously monitors hydrogen sulfide (H2S) in several ppm ranges, delivering highly accurate detection and protection. The unit features one person calibration and can virtually self-calibrate by simply activating a magnetic switch and applying gas. It provides status indication and alarm outputs. Configurations with relays, Modbus, and HART are available to meet many needs.

Ultima® X Series Gas Monitors with X3® Technology

The Ultima X Series Gas Monitors with X3 Technology bring the power of multi-sensing, signal boost and ModBus output to the Ultima X line of MSA gas monitors. The units are crafted from either stainless steel or NEMA 4X-rated plastic, and our patented sensor disconnect-underpower feature allows all sensors to be replaced in hazardous areas without area declassification. The interchangeable smart sensors eliminate the need for reconfiguration, while the use of one circuit board increases reliability. Each sensor can be placed up to 3,000 feet from the monitor, while the scrolling LCD screen displays sensor reading and gas type.   Note: This is a custom product. Please consult your local sales manager or contact Customer Service for configuration details

Ultima® XL/XT Series Gas Monitors

Engineered to provide cost-efficient gas detection, the Ultima XL/XT Series Gas Monitors are simply an outstanding choice. The units boast a hand-held HART port running over 4-20mA output provides convenient setup, calibration and diagnostics. The interchangeable smart sensors eliminate the need for reconfiguration, while local calibration employs LEDS and push-buttons. Indoors or outdoors, some of these explosion-proof models feature infrared technology that eliminates the need for frequent calibrations. Some units operations are based on dual-wavelength, heated-optics technology, which compensates for temperature, humidity and aging effects. The monitors use only one circuit board for increased reliability, and they're easy to install with two-piece field-wiring connectors.
