product description

TCB2 fixed Gas Detector is a multifunctional intelligent gas detection instrument(Different gases can be combined four in one or five in one.)the instrument adopts high performance detection devices and micro computer control technology, and combined with automatic mount of advanced manufacturing technology, the products of both the scene buzzing indicating sound field flashing lights and other functions, and the real-time display of monitoring gas concentration field. 

TCB2 multi-functional gas detector can be in the air gas concentration signal into the electrical signal display and remote transmission, using three wire 4 to 20mA or four RS485 bus output, with long transmission distance and anti-jamming etc.. 

TCB2 fixed Gas Detector can be used in chemical plant, smelting papermaking, gas refrigeration fire,  wastewater treatment, gas ,food, rubber, pharmaceutical scasting , petroleum refining,  mining, municipal fire,communications and other anti explosion, anti poisoning , anti suffocation in the industrial environment
