Product Introduction
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.
Main features
1. The LM-37 handheld mixed insulating gas leak detector displays the current sulfur hexafluoride leakage rate and mixed gas leakage rate.
2. High sensitivity, with a minimum detection limit of up to 0.1ppm.
3. The detection probe of the LM-37 handheld mixed insulating gas leak detector can be bent, enabling the detection of local gas leaks in narrow or hard – to – reach places such as pipelines.
4. Long service life of the sensor.
5. The LM-37 handheld mixed insulating gas leak detector is equipped with a two – level sound and light alarm function.
