Instrument de alarmă de detectare a gazelor GT-TCB6

Descriere

The TCB6 series fixed gas detection alarm is a cutting-edge instrument developed by our company. Featuring high-performance gas sensors and microcontroller technology, it combines advanced SMD manufacturing techniques to deliver exceptional repeatability, precise temperature and humidity control, extended service life, and user-friendly operation.

This product is designed for gas concentration and leakage detection. The detector converts air gas concentration signals into digital displays, supporting three output methods: 4-20 mA current signal, RS485 four-wire bus, or M-BUS two-wire bus. It features long transmission distance and excellent interference resistance.

The detector is designed for gas safety monitoring and alarm control in environments containing flammable gases, including gas pipelines, municipal utility tunnels, research institutions, hospitals, and schools. It is suitable for hazardous areas with explosive flammable gases (Class II A to II C) and temperature groups from T1 to T6.
