Independently developed by DrKSir, the HNAG1000-H2 fixed hydrogen gas detector adopts advanced nano manufacturing and quantum sensing technology to deliver continuous, high-precision hydrogen leakage monitoring. Fully compliant with GB/T 3836.1, GB/T 3836.2 explosion-proof standards and GB/T 4208 IP enclosure rating standards, it features outstanding anti-electromagnetic interference performance, ultra-fast response speed and excellent repeatability.
Widely deployed across hydrogen production plants, hydrogen refueling stations, energy storage power stations, lithium battery workshops, chemical laboratories and other industrial sites with hydrogen explosion hazards. Equipped with multiple industrial signal outputs, it transmits real-time hydrogen concentration data to PLC, DCS and cloud monitoring platforms, enabling automatic safety alarms and predictive risk management for flammable gas environments.
Self-developed sensing unit delivers superior repeatability, ≤6s response time, ≤8s recovery time and 1ppm ultra-fine resolution, precisely capturing tiny hydrogen leaks at early stages.
Ex db Ⅱ C T6 Gb certified flameproof housing fully meets national explosion-proof standards, offering safe operation in Class II C hazardous hydrogen environments.
Dustproof and waterproof enclosure ensures stable operation in harsh industrial conditions, covering -20℃ ~ 60℃ working temperature and up to 95%RH non-condensing humidity.
Comes standard with RS485 Modbus RTU; optional 4~20mA analog signal, 0~10V voltage signal and passive relay alarm contact for seamless compatibility with all mainstream industrial control systems.
Supports wall mounting, pipe clamp mounting and bracket mounting to adapt to diverse layout requirements of hydrogen stations, energy storage plants and manufacturing workshops.
Built-in LED screen displays real-time hydrogen concentration; three colored LED lights indicate normal (green), fault (yellow) and alarm (red) status. One-touch self-test and alarm mute functions simplify on-site operation.
Three multi-function physical keys support one-stop setting of communication address, baud rate, parity bit, stop bit, automatic zero calibration and factory reset without extra controllers.
Low power consumption ≤1W; the hydrogen sensor lasts 2~3 years under normal conditions. Only annual routine calibration is required to maintain consistent detection accuracy.
This gas detector consists of an explosion-proof aluminum housing, multi-layer PCB boards, hydrogen-sensitive sensing element, gas collection hood, permeable filter membrane and digital display panel. The full explosion isolation structural design prevents electric sparks generated by internal circuits from igniting flammable external hydrogen gas. The detachable sensing head design greatly simplifies later maintenance and sensor replacement work.
