BT-GYQ-TCB2 Point-Type Gas Detector (Battery-Powered)

Watch a selected gas at a fixed point when running new signal cables is difficult.

  • Plan power and installation

    The listed built-in lithium battery supports a battery-powered installation; confirm maintenance interval for the chosen configuration.

  • Warn people at the detector

    Natural-diffusion sensing and integrated sound/light indication provide local monitoring and alerts.

  • Share the reading remotely

    RS485, LoRa and GPRS are listed as connection choices; select the output supported by the ordered version.

Confirm gas, battery service plan, hazardous-area requirements and communication option.

Overview

The TCB2 gas detector utilizes high-performance sensing components and microcomputer control technology, manufactured with advanced automated surface-mount processes. It features a built-in audible buzzer and flashing indicator lights, providing real-time monitoring and display of on-site gas concentrations.
This multi-function point-type detector converts airborne gas concentration signals into electrical signals for local display and remote transmission via RS485 (with optional LoRa and GPRS). It is widely applicable in industrial environments requiring explosion, poisoning, and asphyxiation prevention, including chemical plants, smelting and papermaking, refrigeration and firefighting, gas and catering, rubber, wastewater treatment, pharmaceutical casting, petroleum refining, mining and power generation, municipal firefighting, and telecommunications.
