TS12CLR-RS485 is a Commercial Gas Leak Detector with PPM display. This gas detector is suitable for gas detection in Refineries, Chemical plants, LPG stations, Gas Boilers, and Spray-Paints etc. where gas leakage is possible. It reads the gas concentration in air and transmits it to a detection panel over a digital bus. This detector, adopting a catalytic gas sensor, has advantages of good reproducibility, good performance against changes in temperature and humidity. It has a long life span and easy operation. Two alarm levels could be set for warnings (High & Low). Relay output provided can be connected to the Gas Detection Panel. In GAS Detector RS485 and two relay outputs provided. Catalytic sensor is used in this model.
