2. Application
SALEL Portable Gas Detection Alarm can be applied to detect the LEL gas in the coal mine, tunnel and other continuous monitoring environment. When the gas concentration is exceeded, the detector can make sound, light, vibration alarm automatically. It can be portable used by relevant staff, managers, professionals, mobile workers. Also it can be used in the above-mentioned fixed places. Explosion-proof mark for Exibd I.
