▎Product Introduction ：
The RD-3 Hydrogen Leak Detector is a specialized hydrogen detection product independently developed by our company for applications including hydrogen production stations, hydrogen refueling stations, fuel cell system production workshops, and hydrogen testing laboratories. This product adopts a dual-sensor detection mode, integrating both 'high sensitivity for small ranges' and 'high accuracy for large ranges' multi-range leak detection capabilities, fully meeting users' 'one-meter-for-all' testing requirements.
The product features high sensitivity, fast response, and reliable safety performance. With a minimum detection limit of 1 ppm and T₉₀ <1 s, its core components incorporate advanced micro-detection technology and intelligent algorithms to directly convert ambient hydrogen concentration into quantitative readings, enabling precise leak detection across complex working conditions.
▎Key Features ：
1.Micro-leak detection.
2.Second-level response.
3.Four-stage audible & visual alarm.
4.Peak hold function.
5.Data hold function.
6.High-capacity lithium battery power supply with battery level detection and under-voltage alert.
7.Dual alarm modes (audible/visual) with manual mute and variable frequency alerts for different alarm conditions.
