The online combustible gas concentration detector HNAG1000 is suitable for real-time and accurate detection of gas concentration and leakage in various environments. Configured specifically for Sulfur Dioxide (SO2), this Skyeaglee detector utilizes highly sensitive electrochemical technology designed for both atmospheric monitoring (0-1ppm) and extreme industrial flue gas environments (up to 40000ppm).

The device is built to withstand extreme conditions, encased in a premium 316L stainless steel shell. It uses imported catalytic combustion, infrared sensor and microcontroller technology. (Note: Specially equipped with an electrochemical sensor for SO2). It has fast response speed and measurement accuracy. High, stability and repeatability.


Operating the monitor is safe and efficient. 2.5-inch high-definition color screen (TF) displays real-time concentration, temperature, humidity. For hazardous environments, the standard infrared remote control enables operation without opening the cover in dangerous situations.

The system automatically tracks zero point to prevent drift, temperature compensation, multi-level calibration, and can comply with national standards and local and provincial metrology bureau standards in various regions.
The device seamlessly integrates with existing safety networks. Standard bus RS485 and 4~20mA standard signals are output simultaneously, 1 set of relay switching output, optional frequency output 200-1000Hz, 1~5V output, wireless transmission (10-50 kilometers or unlimited distance). The CH4plosion-proof wiring method is suitable for various dangerous places, and is compatible with various control alarms, PLC, DCS and other control systems.


As a hallmark of our industrial design, the Skyeaglee fixed gas detector is engineered for a perfectly clean installation with no visible wires. This strict, wireless-look setup completely eliminates the risk of accidental cable severing in busy industrial sites. Under normal circumstances, to detect harmful gases with a specific gravity greater than that of air, the probe should be installed close to the ground. The detector should be installed at a height greater than 30 cm from the ground to prevent water from splashing in.

Our SO2 gas detectors are trusted across multiple high-risk sectors. Application scenarios include petroleum and petrochemical, chemical plants, smelting plants, steel plants, coal plants, thermal power plants, environmental monitoring, sewage treatment, boiler rooms, Waste treatment plants.

The instrument features an IP Grade of IP66 Protect against splashing water and short periods of rain.
The Warm-up Time is 10S, and the Response Time is T90<10S, ensuring rapid alerts.
The Service Life is 3-5years, and it comes with a 1year Warranty.
