Alarme de détection de gaz sans fil TCB2-W

Description

TCB2-W wireless gas detector transmits the gas concentration signal in the air to the monitoring unit through 433 wireless. It is used in chemical plants, smelting and papermaking, refrigeration, protection contre les incendies, gas catering, rubber, sewage treatment, pharmaceutical casting, petroleum refining, exploitation minière, électricité, protection contre les incendies, municipal administration, communications and other industrial environments that require explosion protection, poisoning protection and suffocation protection and are not convenient for construction and wiring.

The TCB2-W series gas detectors are manufactured using high-performance sensors combined with sophisticated SMD technology. The instrument has good repeatability, resistance to temperature and humidity interference, long service life, and easy operation.

The TCB2-W series gas detectors use two-wire, three-wire or four-wire wiring to detect combustible/toxic gases in the environment.
