Instruction Manual
Product Description:
The GT-SST610LCD gas detector adopts a two-wire non-polar power supply and signal transmission mode, featuring easy installation and convenient wiring. It continuously monitors methane gas 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, strong anti-interference capability and good anti-toxicity resistance.
※It is equipped with an LCD for on-site concentration display and LEDs for on-site status indication: the green LED is on for "Normal", the yellow LED is on for "Fault", and the red LED is on for "Alarm".
※It can be zero-calibrated and calibrated through the matched controller.
※The detector has a built-in infrared receiving module, and on-site settings such as zero calibration and calibration can be performed via an infrared remote control.
※ The sensor module adopts a hot-swappable design, which facilitates installation and maintenance. After replacing the module, it can be used directly without re-calibration.
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.
