Description
Overview
GAOTek handheld gas detector uses international advanced tunable diode laser absorption spectroscopy technology (TDLAS), which can detect methane gas within a certain distance. At the same time, through optimization design and independent research and development, the detection distance and accuracy of the detector are greatly improved, which is the most powerful safety guarantee for gas inspection and leak detection.
