Henan Otywell Electronic Technology Co., Ltd
Descriere
TCB2-W wireless gas detector transmits the gas concentration signal in the air to the monitoring unit through 433 fără fir. It is used in chemical plants, smelting and papermaking, refrigeration, fire protection, gas catering, rubber, tratarea apelor uzate, pharmaceutical casting, petroleum refining, minerit, electricitate, fire protection, 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, durata de viata lunga, si operare usoara.
The TCB2-W series gas detectors use two-wire, three-wire or four-wire wiring to detect combustible/toxic gases in the environment.
