TrueSafe TS12CLR-EX-LEL is LPG/PNG/CNG gas leak detector with LEL display for commercial and industrial segment. It reads gas concentration in air if concentration reaches to hazardous level. It generates alert and send signal to the gas detection panel or BMS. Microprocessor based system reads sensor output and indicates the concentration of gas in atmosphere. It is measured in % LEL (lower explosive limit). This wall mounted unit is designed for permanent installation with replaceable sensor. Detects gases with concentration between 0 to 100% LEL with user defined high and low alarm level.
