CRANBERRY TOWNSHIP, Pa. – The Chemgard Photoacoustic Infrared Gas Monitor with IR sensing technology provides precise, low-cost, high-performance monitoring for one hundred different industrial gases! These gases include 59 standard gases such hydrocarbons, solvents, alcohols, CO2, and CO to name a few.
The Chemgard Gas Monitor uses Photoacoustic Infrared technology which ensures extreme stability, operation for months with virtually no zero drift, and makes it highly selective to the gas of interest. This technology takes a gas sample into the monitor's measurement chamber and the sample is exposed to a specific wavelength of infrared light. If the sample contains the gas of interest, that sample will absorb an amount of infrared light proportional to the gas concentration that is present in the sample. Photoacoustic infrared analysis, however, extends beyond simply measuring the amount of infrared light that is absorbed; this technology actually detects what occurs after the gas is absorbed. Always in motion, gas molecules move around the inside of the measurement chamber, generating pressure. A highly sensitive microphone detects the audible pulse to even the lowest gas levels. With PAIR technology there is no downtime, no fresh air sampling lines are needed, and you have lower detection levels, down to 1 ppm, for faster response.
Three different enclosure styles ensure there is a configuration for wildly different applications. The NEMA 4 version in a rugged metal enclosure is dust and water resistant and provides 4 sturdy, wall-mount tabs on the enclosure back for easy installation. The rack-mount version in standard 19" configuration provides handles on both sides of front panel for easy cabinet extraction. And the explosion-proof version is UL-listed and rated for Class I, Div. 1, Groups B, C, and D areas and comes with 4 wall-mount tabs on the back corners of the unit.
The Chemgard Monitor features easy-to-read displays, three alarm levels, UL 2075 approval and data logging giving users' access to date stamped information on key events including gas readings, alarms and fault conditions.
