Product Description:

The GTYQ-SST607LED type gas detector adopts two-wire non-polar power supply and signal transmission, featuring simple installation and convenient wiring. It continuously monitors methane, combustible gases, and toxic/harmful gases within the lower explosive limit (LEL) range in industrial and commercial environments. Meanwhile, it converts gas concentration and system information into digital signals, which are then transmitted to the gas alarm controller system for identification, display, and processing.


Product Features:

※ The detector adopts high-quality gas-sensing elements, featuring stable performance, high sensitivity, excellent anti-toxicity, and strong anti-interference capability.

※ It is equipped with on-site status indication via LEDs: the green LED lights up for "Normal", the yellow LED for "Fault", and the red LED for "Alarm".

※ Zero calibration and standardization can be performed on it through the matched controller.

※ The sensor module adopts a hot-swappable design, which facilitates installation and maintenance. After replacing the module, it can be used directly without re-standardization.

※ With a dual-cavity structure design, it is suitable for outdoor environments. This design not only facilitates installation and prevents water from entering the cavity but also improves the operational reliability of the gas alarm device.


Application Scenarios:

Widely applied in large shopping malls, large restaurants, food processing factories, pharmaceutical factories, automobile manufacturing plants, small industrial and commercial users (small venues such as snack bars, hairdressing and beauty salons, hotels, public bathhouses and Internet cafes), farmers' markets and other industrial and commercial premises where gas leakage may occur.
