▎Product Introduction ：
The NA-8 Gas Detection Alarm is specially designed for high-position hydrogen detection. Equipped with a highly sensitive sensor and a 6m telescopic probe, it can detect hydrogen at heights up to 8m when extended by an operator. It is suitable for inspecting hydrogen coolers, dryers, circulating fans, oil-water detectors in generators, and hydrogen system pipe joints that conventional leak detectors cannot reach.
▎Key Features ：
1.High-performance catalytic combustion sensor—fast response, high accuracy, long lifespan.
2.Telescopic probe for detecting hydrogen leaks at 8m heights (flanges, joints, etc.).
3.OLED display—self-illuminating, low power consumption, high brightness, wide viewing angle.
4.Adjustable calibration gas concentration for easy user calibration; supports automatic/manual full-range data storage and retrieval.
5.Over-range self-protection to safeguard the sensor; optional automatic/manual data storage and review.
6.Lightweight design (<1kg).
