Apr 12, 2018Apr 12, 2018. Hydrogen gas has a wide flammability range (4% to 74% by volume), detonates (explodes) from 18% to 59%, and is very easily ignited. The major fields of activities exposed to hydrogen are the chemical industries, the oil and gas refining industry, electrochemical research and the manufacturing processes of using or producing hydrogen. Hanwei Electronics Group product line includes a range of state-of-the-art, portable hydrogen detectors, hydrogen gas leak detector …

Jan 26, 2019As the cost suggests, this is certainly a no-frills kit. The donor car is a Ford Sierra (1600cc, 1800cc, 2000cc Pinto) and you should be able to get everything you need from the one car. The Robin Hood company motto is "One kit + one donor vehicle = car on the road."

Apr 01, 2016In recent years, technologies that have developed using methanol as the main raw material include methanol-to-gasoline (MTG), methanol-to-olefins (MTO) and methanol-to-propylene (MTP) processes. The process The following describes a process for producing methanol from natural gas that employs combined reforming for the generation of synthesis ...

The tracer is often used for leak detection, gas-pipeline monitoring and purge testing. This tool gives you information on the percent of LEL, oxygen and carbon monoxide. For methane detection, the RKI Gas Tracer can be fitted with a sensor that reads to 10 parts-per-million and with a thermal conductivity sensor, will read up to 100% of the ...

May 16, 2019Metal oxide semiconductor (MOS) sensors also detect carbon monoxide and function using a gas-sensitive film that is composed of either tin or tungsten oxides. This film reacts when a certain level of toxic gas is present, triggering the device to alert or warn the user.

The tracer gas escapes at a leak opening and then, being lighter than air, permeates to the surface through the soil and pavement. The leak is located by scanning the ground surface directly above the pipe with a highly sensitive gas detector. Although helium is used in the US, the most commonly used tracer gas worldwide is hydrogen (H2).

LPG Gas Detector for Home What is an LPG Gas Sensor? An LPG gas sensor is a one kind of device which is used to sense the presence of a hazardous LPG gas leak in service station, cars, storage tanks and homes.This sensor is attached to an alarm circuit to give an alert to the operators through a buzzer sound in the area where the gas leak is occurring.
