Nkyf Fixed Single Combustible Gas Detector

Product Description

Products Description
The GTYQ-JKD-315 series industrial and commercial point type combustible gas detector (hereinafter referred to as the detector) is a new type of gas detection instrument produced by our company. This machine is made using high-performance gas sensitive components and microcontroller technology, combined with advanced SMT technology. It has good repeatability and temperature and humidity characteristics, as well as long service life and easy operation. It is suitable for environments where gas may leak, such as small restaurants, shopping malls, and underground comprehensive pipe galleries. When the gas concentration in the environment exceeds the set concentration, an alarm will be triggered through indicator lights and buzzers. At the same time, it can drive electromagnetic valves, fans, and other equipment to protect the safety of users and property.
This detector has the characteristics of easy installation, compact structure, low cost, explosion-proof, stable and reliable, easy operation and maintenance, and flexible wiring.
The design, manufacturing, and calibration of this product comply with the following national standards:
(1) GB 15322.1-2019 (Combustible Gas Detectors for Industrial and Commercial Purposes);
(2) GB/T 20936.1-2017 "Gas detectors for explosive atmospheres - Part 1: Performance requirements for combustible gas detectors";
(3) GB/T 20936.2-2017 "Gas detectors for explosive atmospheres - Part 2: Selection, installation, use, and maintenance of combustible gas and oxygen detection";
(4) GB 3836.1-2010 Explosive Atmospheres Part 1: General Requirements for Equipment;
(5) GB 3836.2-2010 Explosive Atmospheres Part 2: Equipment Protected by Explosion proof Enclosures "d";
