BT-AEC2689 series laser methane telemeter adopts tunable laser spectroscopy (TDLAS) technology, which can remotely detect methane gas leakage at high speed and accurately. The operator can use this product to directly monitor the methane gas concentration in the visible range (effective test distance ≤ 150 meters) in a safe area. It can fully improve the efficiency and quality of inspections, and make inspections in special and dangerous areas that are inaccessible or difficult to reach safe and convenient, which provides great convenience for general safety inspections.
