Instruction Manual
Product Description:
The GTYQ-SST623LCD gas detector continuously monitors methane, combustible gases, and toxic gases within the lower explosive limit (LEL) range in industrial and commercial environments. It converts the gas concentration into a 4-20mA signal, which is then transmitted to a gas alarm controller or DCS (Distributed Control System) for display and processing.
Product Features:
※ The detector adopts high-quality gas-sensing components, featuring stable performance, high sensitivity, and excellent anti-toxicity resistance.
※ It has a high protection level and is suitable for harsh environments.
※ LCD concentration display and LED status indication.
※ It is equipped with a built-in infrared receiving module, allowing various parameters to be set via an infrared remote control for convenient maintenance.
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.
