Photoacoustic gas monitor eliminates interference from water vapors
- July 25, 2011
- Product Release
- Safety
The PA4000 photoacoustic infrared gas monitor from General Monitors provides gas monitoring while eliminating interference from water vapors.
Designed with a photoacoustic, infrared (IR) sensor to monitor gases including hydrocarbons, solvents, alcohols, CO2, and CO, the unit is selective to the gas of interest and can operate for months with almost no drift.
The gas monitor's proprietary sensing technique determines the amount of water vapor in the sample and subtracts it from the gas reading. This technique allows the gas reading to be stable with no compromise to measurement sensitivity.
With the capability to measure 0 to 1,000 PPM depending on the specific configuration, the unit is accurate to ±2 PPM at 1 to 100 PPM and ±10 percent of reading from 100 to 1,000 PPM. Featuring a 2-PPM sensitivity and 1-PPM resolution, it detects concentrations as low as 0.01 PPM.
The gas monitor operates from 32 to 122 degrees F and can be stored from -67 to 158 degrees F.
