Instruction Manual
Product Description:
The GTYQ-SST611LED gas detector continuously monitors methane and propane gases within the lower explosive limit (LEL) range in industrial and commercial environments. 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 and high sensitivity.
※ Excellent anti-poisoning performance and strong anti-interference capability.
※ Two-wire non-polar connection, no need to distinguish between positive and negative poles, enabling simple and convenient installation and cost-effective wiring.
※ It can be zero-calibrated and calibrated through the matched controller.
※ LED on-site status indication: the green light is on for "Normal", the yellow light is on for "Fault", and the red light is on for "Alarm".
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.
