Instruction Manual
Executive Standard:
The GT-SST607LCD type gas detector adopts two-wire non-polar power supply and signal transmission, featuring simple 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, excellent anti-toxicity, and strong anti-interference capability.
※ It is equipped with on-site concentration display via LCD and on-site status indication via LEDs: green LED lights up for "Normal", yellow LED for "Fault", and red LED for "Alarm".
※ Zero calibration and standardization can be performed on it through the matched controller.
※ The detector has a built-in infrared receiving module, allowing on-site settings such as zero calibration and standardization via an infrared remote 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.
※ The dual-cavity structure design makes it suitable for outdoor environments, facilitates installation, prevents water from entering the cavity, and improves the operational reliability of the gas alarm device.
Application Scenarios:
Widely applied in large shopping malls, restaurants, food processing plants, pharmaceutical factories, automobile manufacturing enterprises, small commercial and industrial premises (snack bars, hairdressing and beauty salons, hotels, public bathhouses, Internet cafes and other small venues), farmers' markets and other commercial and industrial places where gas leakage may occur.
