The LM-37 Handheld Mixed Insulating Gas Leak Detector is used for leak detection or sealing performance testing of electrical equipment and other devices containing SF₆ mixed insulating gas. Utilizing the principle of infrared absorption spectroscopy to analyze and detect SF₆ gas, it offers high sensitivity, excellent stability, and rapid response.

▎Key Features ：

1.Displays current SF₆ leakage rate and mixed gas leakage rate.

2.High sensitivity with minimum detection limit of 0.1 ppm.

3.Flexible detection probe can be bent to detect localized gas leaks in pipes or other narrow/hard-to-reach areas.

4.Long sensor service life.

5.Two-stage audible and visual alarm function.
