Gas Detectors

The S4000CH Intelligent Sensor is a microprocessor-based transmitter designed for use with General Monitors industry-leading catalytic bead sensors. It monitors combustible gases and vapors within the lower explosive limit (LEL) and provides status indication and alarm outputs. Complies with ANSI/ISA 12.13.01-2000 performance requirements for combustible gas detectors.

The microprocessor-based, infrared Ultima XIR gas detector is precisely engineered to continuously monitor for combustible gases and vapors. The unit features DuraSource Technology, which offers improved IR life, and a HART port for easy output access. The explosion-proof stainless steel monitor works indoors or outdoors and features infrared technology that eliminates the need for frequent calibrations. Its operations are based on dual-wavelength, heated-optics technology, which compensates for temperature, humidity and aging effects. The unit uses only one circuit board for increased reliability, and the sensor life isn't reduced by exposure to gas. The LCD screen provides scrolling information, while optional quick-check LEDs provide increased visibility.

The 610A is a system for continuously monitoring combustible gas (hydrocarbon) concentrations in four locations. The system consists of four General Monitors remote catalytic bead sensing assemblies and a solid-state controller. The controller features four independent channels, each having its own circuitry. The 610A features a digital display of gas concentrations in % LEL (0-99% lower explosive limit) for each channel.

The IR5500 is an open path infrared (IR) gas detector that continuously monitors for flammable gas leaks over large open areas. It monitors in both the LEL-m and ppm-m ranges to detect both small and large leaks. The IR5500 offers the benefits of early detection with its high sensitivity to gas concentrations at the ppm levels.  This feature allows it to alarm faster than an LEL-only detector. Digital display and adjustable mounting arms ensure easy alignment. Factory calibrated for low-maintenance operation.

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. 

Every feature of the PrimaX IR Gas Transmitter is designed with reliability in mind to withstand the most challenging environmental conditions through out the product’s life. MSA’s PrimaX IR Gas Transmitter offers LEL (Lower Explosive Limit) combustible gas detection through a patented PrimaX Gas Transmitter IR dual source design. A redundant IR source provides reliability and uninterrupted monitoring should a source failure occur. Furthermore, the possibility of obscurations due to rain, fog, dirt, dust, and other environmental conditions is minimized due to dual source design.

The IR4000S Single-Point Monitor is a display and user interface for the IR400 point IR gas detector. The monitor allows local calibration and displays gas concentration. Relays are optional. The relays provide output for Alarm, Warn, and Fault conditions.

The IR4000M Multi-Point Gas Monitor can be used as an integrated combustible gas detection system, with capacity to connect eight point IR or open path gas detectors and read their status with one command. The highest current % LEL among all connected detectors is shown continuously during normal operation. An extensive set of menus are easily navigated using a magnetic switch to request the status and configuration data stored by the IR4000M.

Simply connect the convenient ToxGard II Gas Monitor to a power source and a remote sensor, and it's ready to detect toxic gases, combustible gases and oxygen deficiency. The indoor/outdoor unit is housed in a rugged NEMA 4X enclosure and features a large LED screen, three levels of alarm and a failsafe fault relay output.

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.
