Gas Detectors

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.

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 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 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.

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.

Designed to detect gases indoors or outdoors, our PrimaX P Gas Transmitter measures oxygen and toxic and combustible gases. The flameproof transmitter is housed in a powder-coated aluminum enclosure that will protect it in extremely dangerous conditions. The unit also features a large, easy-to-read LCD screen and three LED status indicators for up-to-the-second reporting. The transmitter attaches to an integral mounting plate for easy installation, and it can be easily calibrated using the built-in keypad. It uses a 4-20 mA output signal to transmit its data, and it can also be configured to use HART digital communication. With easily replaced plug-in sensors, the PrimaX P transmitter is suitable for laboratories, chemical plants, power plants and several other industry settings.

Indoors or outdoors, our PrimaX I Gas Transmitter provides dependable, accurate gas detection. The transmitter detects toxic gases and oxygen and is housed in an antistatic, reinforced nylon enclosure. It also has a large, easy-to-read LCD screen and attaches to an integral mounting plate for easy installation, while the built-in keypad makes for quick, simple calibration. To transmit data, the unit uses a 4-20 mA output signal and can also be configured to use HART digital communication. With easily replaced plug-in sensors, the PrimaX I transmitter is suitable for laboratories, chemical plants, power plants and several other industry settings.

Designed to detect flammable gas or vapor, the stainless steel Series 47K gas sensors offer a cost-effective way to detect hazards in the air. The sensors come in poison resistant and high-temperature versions, and have three- or five-wire connection.

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.

Designed to meet a variety of demanding applications, from wastewater facilities, to light industry and commercial applications, the TRIGARD Gas Monitoring System features MSA's precision craftsmanship and detects chlorine, sulfur dioxide and other toxic and combustible gases. The adjustable-range unit also detects oxygen deficiency and enrichment. AC or DC powered, the system features a highly visible LCD screen and simple push-button calibration. Boasting sturdy NEMA 4X design and a single board, the unit offers multiple sensor mounting options. Our patented sensor disconnect-underpower feature allows all sensors to be replaced in hazardous areas without area declassification, while interchangeable smart sensors are pre-calibrated for installation right out of the box.

The TriGas X5000 Monitoring System is an integrated gas detection solution that helps plant operators comply with NFPA 820. The system monitors for combustible gases, hydrogen sulfide and oxygen with on-board alarming and communication interface to plant and remote location control stations.

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 stable, durable Chemgard Photoacoustic Infrared Gas Monitor is purpose-built and detects minute amounts of a wide variety of gases. Three different enclosure styles ensure there is a configuration for wildly different situations. The instrument typically draws the gas sample via an internal pump, which allows the unit to be mounted in a convenient location if the area to be monitored is inaccessible. The unit can be expanded to monitor up to 8 locations, while an easy-to-read display shows gas concentrations and 3 levels of alarms.
