The HNAG1000-EX Fixed Insertion Combustible Gas Detector is meticulously engineered for the continuous, real-time detection of combustible gas (EX) concentrations and leakages directly within industrial pipelines, flues, and enclosed furnaces. By utilizing advanced catalytic combustion technology and a high-speed processing circuit, this insertion-type analyzer delivers an exceptionally fast response speed (T90 < 10s) and high measurement precision, ensuring optimal safety in hazardous locations.
Designed to withstand extreme industrial conditions, this pipeline gas detector features a heavy-duty stainless steel shell that provides superior resistance to corrosion and mechanical impact. The insertion probe length is highly customizable based on your specific pipe diameter, ensuring that the sensor is perfectly positioned in the gas flow for accurate readings. The entire unit boasts a strict explosion-proof design, making it fully certified for highly combustible and volatile environments.
The device is equipped with a high-precision, passive-type sensor that remains highly sensitive and unaffected by pipeline vibrations. For immediate on-site alerts, the detector features an integrated sound and light alarm light. Its high-brightness luminous tube ensures clear visual warnings even in dusty or dark facilities. Furthermore, the standard infrared remote control allows operators to perform parameter adjustments and real-time monitoring without opening the stainless steel enclosure, ensuring maximum safety.

The insertion detector is highly adaptable for various on-site installation statuses, whether mounted directly on a furnace wall or along horizontal/vertical pipelines.

The internal circuit provides clearly labeled pin definitions for easy and fast wiring. It supports standard RS485 and 4-20mA signal outputs, perfectly integrating with PLC, DCS, and other monitoring systems.


To meet the demands of modern smart factories, the detector offers optional wireless signal outputs. It can seamlessly transmit real-time data to mobile devices, computer viewing platforms, and gas alarm controllers via Custom 4/5G Upload, LoRa P2P, or Bluetooth Tx.
