Press Release Summary:
Chemgard Infrared Gas Monitor offers monitoring ranges as low as 0-10 ppm to as much as 100% by volume for select gases. It can simultaneously detect either oxygen, carbon monoxide or combustible gas along with one of over 100 infrared-active compounds. Monitor is available in NEMA 4 wall mount, 19 in. rack mount, or explosion-proof enclosure. Each monitors from 1-8 sample point locations and provides 3 levels of alarm control.Original Press Release:
MSA Chemgard(TM) Infrared Gas Monitor for the Plastics and Paint Industries
The Chemgard(TM) Infrared Gas Monitor from MSA Instrument Division is a complete, flexible platform ideally suited for gas monitoring in the plastics and paint industries. The Chemgard Monitor can detect toluene and other aromatics, alcohols, chlorinated hydrocarbons, ketones and esters used in these industries, as well as many other compounds. Applications
include general air monitoring for health, solvent recovery applications and monitoring of storage areas.
With monitoring ranges from as low as 0-10 ppm to as much as 100% by volume for select gases, including LEL monitoring, a durable NEMA 4 enclosure, and advanced photoacoustic infrared sensing technology, the Chemgard Monitor provides accurate, reliable low-level leak detection and process monitoring.
The Chemgard Monitor's photoacoustic infrared sensing, a high-performance, low-cost gas detection method, is the technology of choice for low parts-per-million (ppm) or parts-per-billion (ppb) monitoring. It is extremely stable, with virtually no zero drift, and greatly reduces interference effects from background gases and humidity.
Featuring an electrochemical or catalytic bead auxiliary sensor option, the Chemgard Monitor can simultaneously detect either oxygen, carbon monoxide or combustible gas, along with one of over 100 infrared-active compounds. The auxiliary sensor gas concentration can be monitored through the unit display or a 4-20 mA analog output, and the sensor fits conveniently inside the standard Chemgard Monitor enclosure.
The Chemgard Infrared Gas Monitor is available in a NEMA 4 wall mount, a 19" rack-mount, or an explosion-proof enclosure, all with four, front-panel button controls. Each version can monitor from one to eight sample point locations and provides three levels of alarm control.
