Described as ideal for a number of industries and applications, a new Gas Monitoring Video from General Monitors explains the gas detection principles behind the company’s PA4000 Photoacoustic Gas Monitor and its application across a wide range of hazardous environments.

The video illustrates how the PA4000 can be deployed in these many industrial environments to protect people, equipment, and facilities.

Offering a low maintenance, cost-saving solution in situations where vapor interference or contaminants preclude the use of other measurement techniques, the reliable PA4000 Photoacoustic Gas Monitor provides precise, high-performance gas monitoring.

The product features dependable infrared (IR) sensing technology and is ideal for use in chemical refineries, mining and metals fabrication, agriculture, electric utilities, welding shops, indoor air quality monitoring, and building maintenance. It is designed with an advanced photoacoustic IR sensor to monitor a variety of gases and vapors including alcohols, carbon dioxide, carbon monoxide, vinyl fluoride, acetone, butane, ethylene, toluene, and xylene.

General Monitors notes that the PA4000 is stable and highly selective to the gas of interest and can operate for months with virtually no drift – and eliminates a common problem with infrared analyzers: cross-sensitivity to water vapor.

The device features a proprietary sensing technique that determines the amount of water vapor in the sample and subtracts it from the gas reading. As a result of this technique, the instrument is able to detect analyses in the ppm range.

Easy to install, operate, and maintain, the principles behind the PA4000 – as well as its application across a whole range of environments – are now explained in the new video from General Monitors.
