PGas-21-CO 0-500ppm CO Gas Tester Analyzer Portable Carbon Monoxide Detector. Brief introduction. PGas-21 single-gas detection alarms are used to detect the concentration of oxygen and toxic, harmful or flammable gas in different environments. If the detected value reaches or exceeds the preset alarm limit, alarms will be immediately given out.

Industrial Gas Systems Wherever toxic or combustible gases are part of an industrial process or a by-product of it, they pose a threat to people, property and productivity. Honeywell Analytics offers a complete line of rugged, reliable, fixed-point gas detectors to serve as your first line of defense against gas …

The VARIOTEC ® 460 Tracergas was developed especially for leak detection on underground pipes by using tracer gas. It is characterised by an outstanding price to performance ratio. The extraordinarily low cross sensitivity of the gas-sensitive semiconductor (SC) with regard to moisture and methane ensures an absolutely sure result and a resolution down to 0.1 ppm H 2.

Dräger Polytron ® 8700 IR The Dräger Polytron ® 8700 IR is an advanced explosion proof transmitter for the detection of combustible gases in the lower explosion limit (LEL). It uses a high performance infrared Dräger PIR 7000 sensor, ...

Where To Buy. RKI is located in Union City, California and began in 1994 with the belief that distributors and customers deserve a permanent reliable source for advanced gas detection instruments and advanced gas sensors.

The tracer gas passes through leaks in the system under test to the surrounding atmosphere where it is drawn into the leak detector through an orifice-type probe. The leak detector, upon sensing the increase of tracer gas in the probe inflow, registers an indication of a leak in the system.

Oct 01, 2019Linde Engineering (Pullach, Germany; ) has developed a process to recover helium, hydrocarbons and purified carbon dioxide from natural gas, while conditioning the natural gas for pipeline transport by adjusting the water and heavy-hydrocarbon dew point and the CO2 concentration.

Nov 06, 2020Modular solutions for carbon neutral shipping Methanol can be used in polymer electrolyte membrane (PEM) fuel cells that operate with an upstream reformer. Through steam reforming, the system produces hydrogen, which reacts with oxygen in the fuel cell to produce the electricity required for the propulsion as well as the on-board power supply.
