IP66 protection class. Confirm gas combination, sampling version, alarm thresholds and output protocol.

Overview

TCB2-F fixed Gas Detector is a multifunctional intelligent gas detection instrument, 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 and flashing lights , and the real-time display of monitoring gas concentration field. TCB2-F 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-F fixed Gas Detector can be used in chemical plant, smelting, fire, gas refrigeration and papermaking wastewater treatment, food, rubber, pharmaceuticals, petroleum refining, casting, mining, communications and other municipal fire power to anti explosion, poisoning prevention, anti suffocation in the industrial environment. this model candetect 1-4 different gases。
