Methane Gas Detection & Sensors

Methane (Hydrocarbon) is an odorless gas with the chemical formula of CH4. Methane is flammable and combustible with oxygen. Methane is one of the primary components of natural gas, so it is readily found in the environment and used in a diverse range of applications. Methane has a lower explosion limit of 5.0%.

Since methane has no color or odor but can seep in through cracks in the floor, combustible gas detector is essential for any plant or refinery where methane is present.  Our portable explosive gas detector can test the methane , butane and probane ,etc gases concentration and make alarms to warn workers safety.

Besides our own gas detectors, we have customized many kinds of gas detectors for our customers in the world. We can customize the plastic enclosure, pcb for gas detectors, and the whole gas detectors according to customer's requirement. 



Beijing Dashiweiye Tech Co., Ltd. Is a technology innovation enterprise specialized in portable gas detectors manufacturing and customization for personal monitoring using in industry and household.   We also builded a new company "shiantech" in 2013 year to specialized in the production for the gas detectors.
