Dual Channel NDIR CH4(Methane) sensor

Methane (CH4) gas is one of the important energy sources in the home and industry, but it has a risk of warming and potential explosion of the earth, which requires severe management.

TES0702 is an ultra -compact NDIR sensor module equipped with a digital interface for CH4 (methane) measurement. In particular, it can be used for the concentration measurement of CH4 (methane) and gas leakage detection in power plants, LNG bases, mines, tunnels, gas stations, and houses that require accuracy in low concentration environments.

TES0702 provides high accuracy and stability at a reasonable price, and a pre-calibrated module, which can measure the CH4 (methane) concentration up to 2,000 ppm. (Other maximum concentrations are provided at request.)
