Gas Detectors

MSA Ultima Series XE Gas Detector

Ultima® X Series Gas Monitors

Designed to provide thorough, continuous monitoring of many hazardous gases, the indoor/outdoor Ultima X Series Gas Monitors offer excellent performance and MSA quality craftsmanship. DuraSource™ Technology offers extended sensor life, while HART provides convenient setup, calibration and diagnostics. HART also allows for existing component install and wiring to be used. A single circuit board increases reliability, while our patented sensor disconnect-underpower feature allows all sensors to be replaced in hazardous areas without area declassification. The units are crafted from either stainless steel or polycarbonate, and the interchangeable smart sensors eliminate the need for reconfiguration. Our scrolling LCD screen display sensor reading and gas type, while the calibration process includes date stamping and the ability to calibrate locally or remotely.
MSA S4000TH Hydrogen Sulphide Gas Detector Unit - front view

S4000TH H2S Gas Detector

The S4000TH Intelligent Gas Sensor is a microprocessor-based transmitter designed for use with General Monitors' thin film metal oxide semiconductor (TFMOS) sensors to detect H2S gas. The unit features one person calibration and can virtually self-calibrate by simply activating a magnetic switch and applying gas. It detects hydrogen sulfide in 0-20 ppm, 0-50 ppm or 0-100 parts per million (ppm) levels over a wide temperature range. 
MultiGard™ 5000 Multipoint Gas Sampling System

MultiGard™ 5000 Multipoint Gas Sampling System

The economical, efficient MultiGard 5000 Gas Sampling System uses auto-standardization and flexible sample point order to analyze gas from up to 32 locations. Maintenance and calibration are made easy because all the work is performed at a single location, while also ensuring personnel don't have to enter the monitored area. The unit directly connects to Modbus TCP/BACnet IP networks, which allows communication to other equipment or controllers. The system allows secure viewing at one's personal computer. The screen provides easy access to scroll-down menus and visual indicators of sensor condition.
IR700 Point IR Carbon Dioxide Gas Detector

IR700 Point IR Carbon Dioxide Gas Detector

The IR700 Infrared (IR) Point Detector is a microprocessor-based carbon dioxide gas detector that continuously monitors for CO2 in ppm levels. All electronics are contained within an explosion-proof housing so that the IR700's detector information can be processed locally. The IR700 operates with a 4-20 mA signal, which is proportional to 0 to 100% full scale. Configurations with analog output, Modbus and HART are available. Modbus and HART data can be used for predictive maintenance.
IR4000S-CO2 Single Point Gas Monitor

IR4000S-CO2 Single Point Gas Monitor

The IR4000S CO2 Single-Point Monitor is a display and user interface for the IR700 carbon dioxide gas detector. The monitor allows local calibration and displays gas concentration. Relays are optional. The relays provide output for Alarm, Warn, and Fault conditions. 
Ultima® X Series Gas Monitors with X3® Technology

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 SafeSwap 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

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 4-20 mA output which 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.
