610A Four Channel Combustible Gas Monitor

610A Four Channel Combustible Gas Monitor

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.
Catalytic Bead Sensors

Catalytic Bead Sensors

The General Monitors catalytic bead gas sensors are well known for their sensitivity, reliability and longevity and make them the first choice for most users of the catalytic oxidation gas detection principle. Every component is manufactured in-house to ensure optimum performance. Careful matching of the active and reference elements ("beads") result in a sensor that has negligible zero drift with respect to changes in humidity, pressure, and temperature.
IR5500 Open Path Infrared Gas Detector

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.

H2S Gas Sensors and Accessories

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.

9010/9020 Controller

9010/9020 Controller

The 9010/9020 SIL controller comes with advanced design and innovative features for monitoring up to 20 channels. The 9010 controller operates with one independent sensor, while the 9020 operates with two independent sensors per control module. Each module comes with an independent AC/DC power supply for increased system reliability. Both units feature full internal diagnostics, which minimize false alarms and unexpected down time. The controller powers up the remote gas detectors, while its large four-digit LCD and LED provide crucial information such as gas concentration, alarm status and more. The 9010/9020 LCD controller monitors up to 20 channels and comes with an independent power supply. The LCD version has approvals for FM (North America) and CCCF (China) whereas the 9010/9020 SIL controller is ATEX and  SIL 2 certified.
