Hazardous Gas Monitoring

Critical Systems provides Hazardous Gas Monitors for virtually all of the gases used or generated in the Semiconductor, Solar, MEMS, NANO and other high tech industries. Transmitters and monitoring systems are used for gas detection in cleanroom areas, in and around process tools, and on Critical Systems professionally reconditioned gas cabinets for cabinet shutdown in the event of a cabinet gas leak.

Our sample-draw Transmitter offers an array of sensor technologies unmatched in the industry, including unique offerings, such as our hydrogen-specific or LEL versions.

The long life high capacity pump and wide variety of sensing elements are replaceable in a few seconds, with no tools required! The smart sensors retain all calibration and sensor-specific data in non-volatile memory, so sensors can be hot-swapped in the field with no programming required. The sensors also retain calibration information, which means they can be conveniently calibrated separate from the Transmitter, avoiding transport of calibration gases to the field location. Our firmware automatically corrects for long-term zero and span “drift” minimizing maintenance and maximizing reliability.

Our Hazardous Gas Transmitter can be used as a stand-alone device, offering a number of communication protocols to existing PLC systems, or can be integrated with CSI’s series of single and multi-channel controllers.

All Hazardous Gas Transmitters include a large, easy to read integral LCD display, tri-color bar graph for visual notification of alarm status, programmable low and high alarm relays, and fault relay. Pump flow is self-tuning for maintenance-free operation. Because all Transmitter base units are identical, sensors can be interchanged with no programming or tools required, resulting in maximum flexibility to the user.
