The Gas Concentration Alarm, also known as the Combustible Gas Leak Alarm, is specifically designed to monitor the concentration of natural gas leaks in the environment. When a natural gas leak occurs, our alarm can display the real-time concentration of the leaked gas. If the concentration exceeds the preset alarm threshold, the device will trigger audible and visual alarms. This instrument is a fixed-installation gas alarm system, consisting of two main components: the controller and the detector. The controller is placed in the duty room and features an LCD screen to display the real-time concentration of natural gas leaks. When the concentration surpasses the set alarm value, the device will activate audible and visual alarms, which are categorized into two levels: low alarm and high alarm. The detector is installed at the gas leak site. Our detectors come in several configurations: standard type, display type, and display with audible/visual alarm type. The standard type does not include on-site concentration display or audible/visual alarms. The display type includes on-site concentration display, while the display with audible/visual alarm type includes both on-site display and audible/visual alarms.

Performance of the Gas Concentration Alarm, Combustible Gas Leak Alarm:

Complies with national standards and holds certifications such as the CMC Measuring Instrument Production License and Explosion-Proof Certification.

Explosion-proof, lightning-proof, anti-static, reverse connection protection, resistant to EMI and EMC electromagnetic interference, and capable of withstanding surge current impacts.

Supports divided-line or two (four)-wire 4-20mA standard signal output, voltage output, and two sets of relay switch outputs.

Also features standard bus-based RS485 output (RTU format), with an optional integrated audible and visual alarm.

Optional transmission methods include wired transmission, LAN, internet, and wireless transmission (2 km, 5 km, or unlimited distance).

Wireless transmission options include 433, GPRS, WiFi, and other methods.

Comes standard with an infrared remote control for safe operation in hazardous environments without opening the cover. The remote control has a range of 15 meters and is simple and practical.

Units can be switched between each other, with automatic zero-point tracking to prevent drift and multi-level calibration. Supports OEM or ODM customization.

Can communicate with a computer, allowing real-time monitoring of on-site probe concentrations via upper computer software, as well as data storage, analysis, and printing on the computer.
