Portable Combustible Gases Detector

Gas detectors generally monitor gas concentrations based on the lower explosive limit. This is because even if a gas is present at concentrations exceeding the upper explosive limit, if a gas leakage occurs into the atmosphere, the gas will be immediately diluted and diffuse, bringing concentrations to within the explosive range. The unit % LEL is frequently used to express a concentration with respect to the lower explosive limit (100 % LEL).

Combustible Gas Detector

• Compact size and light weight, the combustible gas detector adopts double body protection, safer for operation and portable to carry with you.
• Flexible metal hose and metal induction shield can reduce interference, which is suitable for all kinds of detection applications.
