Instruction Manual
Product Description:
The GT-SST613LED gas detector continuously monitors methane gas within the lower explosive limit (LEL) range in industrial and commercial environments. It converts gas concentration and system information into current 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 components, featuring stable performance, high sensitivity, and excellent anti-toxicity resistance.
※ LED on-site status indication: green light on for "normal", yellow light on for "fault", and red light on for "alarm".
※ The sensor module features a hot-swappable design, facilitating easy installation and maintenance. After replacing the module, it can be used directly without the need for recalibration.
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.
