General Monitors® S5000 Gas Monitor
The General Monitors S5000 Gas Monitor is the ultimate gas detector for extreme environments needing to detect oxygen, toxic and combustible gases
It operates over a wide temperature range using a variety of gas sensing technologies. Breakthrough XCell® gas sensors with TruCal® technology extends calibration cycles up to 24 months and actively monitors sensor integrity for ultimate peace of mind.

SMC 5100 Series Toxic Gas Detector
The SMC 5100-XX-IT gas detector monitors toxic gases such as Hydrogen Sulfide, Carbon Monoxide, Nitrogen Dioxide, Ammonia, Oxygen Deficiency, and others. The detector requires calibration only every six months, cutting operating costs and time. As part of the SMC Sentry IT platform, the detector can be remotely diagnosed and calibrated via Remote Sensor Capability.

ULTIMA® X5000 Gas Monitor
The ULTIMA® X5000 Gas Monitor is the future of gas detection for oxygen, toxic and combustible gases. MSA XCell® gas sensors with TruCal® technology offer calibration cycles up to 24 months (local calibration respected). The gas transmitter's advanced, multi-lingual OLED display is easy to read and the unique touch-screen interface makes it simple to navigate.

IR5500 Open Path Infrared Gas Detector
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.

FL500 UV/IR Flame Detector
The FL500 UV/IR Flame Detector monitors for radiation emitted by a flame in both the ultraviolet (UV) and infrared (IR) spectral ranges. This UV/IR combination provides a fast response time and increased false alarm immunity against sources of radiation for reliable protection.

Senscient ELDS™
Open Path Gas Detector
Senscient open path gas detector ensures best in class false alarm rejection
The Senscient ELDS laser-based open path gas detector is available for a wide range of toxic and flammable gases. The Senscient ELDS uses 'SimuGas' self-testing to eliminate employees entering hazardous areas for gas checks. Nuisance false alarms are virtually eliminated with its breakthrough Harmonic Fingerprint processing.

9010/9020 SIL Control System
9010/9020 SIL controller offers a maximum flexibility in conjunction with a wide variety of detectors. It operates with either one (9010) or two (9020) independent channels per control module which makes it logically independent, highly economical and therefore best suited for smaller gas detection
installations. The dual channel capability allows a high density packaging of up to 20 points in a single 19” rack.
Its new SIL compliant design offers a higher safety function to increase the protection level for facilities and people.
A high level of reliability is ensured as each control module is fitted with an independent AC/DC power supply unit and
logic circuit with software validated according to ATEX Directive.

SENTRY io® Controller
Powerful fire and gas detection controller for mid-size industrial applications
The SENTRY io Controller offers a robust, easy to use platform for nearly any application and skill level. Modern touchscreen HMI supports intuitive setup, operation, and troubleshooting workflows. Guided setup and auto-recognition of MSA and General Monitors® flame and gas detectors through HART saves valuable time during setup and configuration.

Chillgard® 5000 Refrigerant Leak Monitor
The Chillgard 5000 Refrigerant Leak Monitor provides the earliest level of detection of costly refrigerant gas leaks in mechanical equipment rooms. Sampling system with patented photoacoustic infrared (PAIR) technology detects leaks as low as 1 part per million (ppm). Intuitive, touchscreen user interface makes it easy to operate. Predictive maintenance and diagnostics keep you operational.

Observer® i Ultrasonic Gas Leak Detector
Instantly detect pressurized gas leaks with this high-precision, omni-direction acoustic detector utilizing Gassonic® ultrasonic technology. Works even when traditional methods of gas detection are unsuitable or dependent on ventilation. The Observer-i UGLD provides an industry-leading detection range (up to 28 m) reducing the number of detectors required.

Bacharach’s MGS-450 Gas Detector
MSA Bacharach’s MGS-450 Gas Detector makes compliance with refrigeration safety codes simple and easy, saving time and money on equipment and installation. Using the MGS-400 App, users can intuitively use, commission and maintain their gas detection system without the need for specialty training or tools. Pre-calibrated sensor modules simplify maintenance, take minutes to exchange and do not require the use of calibration gas.
