The HNAG1000-5H online combustible and toxic gas concentration detector is designed for real-time, highly accurate monitoring of gas leakage in harsh industrial environments. It integrates temperature, humidity, and multiple gas targets (VOCs, CO2, CH2O) into one robust unit.
Equipped with top-tier imported sensors (such as Honeywell & City) utilizing catalytic combustion, electrochemistry, and Infrared NDIR technology. This ensures rapid response (T90<10S) and exceptional repeatability. The plug-and-play internal structure allows for easy maintenance without specialized tools.
This industrial gas analyzer supports multiple signal outputs to seamlessly integrate with your existing DCS, PLC, or DDC systems.
Wired: Standard 4-20mA signal and RS485 (MODBUS RTU protocol).
Wireless Modules (Optional): Support for GPRS, 4G, LORA, ZigBee, and Bluetooth for unlimited remote data monitoring.
Safety is our priority. The unit features an intrinsically safe circuit design with an IP66 protection grade, effectively guarding against splashing water and short periods of rain. It holds the Ex d IIC T6 explosion-proof certification, making it ideal for petroleum, chemical plants, and oil pipelines.
The standard infrared remote control allows operators to adjust settings without opening the cover in hazardous areas. A 2.4-inch TFT color screen simultaneously displays 4 gases along with temperature and humidity. We also provide optional flow cells for pump-sampling lines and various power adapters.


With over 14 years of experience in the gas detection industry, Skyeaglee provides tailored solutions for diverse working conditions. Depending on the specific gravity of the target gas, detectors can be wall-mounted, pipe-mounted, or ceiling-installed.
