▎Product Introduction ：
The NA-1⁺ Portable Hydrogen Leak Detector adopts a dual-sensor detection mode, combining 'small range with high sensitivity' and 'large range with high accuracy' for dual-range leak detection. It features real-time measurement display and parameter storage. When gas concentration reaches or exceeds preset alarm limits, immediate alarms are triggered. Suitable for hydrogen-cooled generators, hydrogen production stations, and hydrogen pipeline leak detection in power plants. Certified as intrinsically safe for explosive atmospheres (Ex ib IIC T3 Gb). Complies with GB/T 3836.1-2021 (Explosive Atmospheres - Part 1: General Requirements) and GB/T 3836.4-2021 (Explosive Atmospheres - Part 4: Equipment Protection by Intrinsic Safety 'i'). Approved for Zone 1 & 2, Group IIA-IIC, T1-T3 hazardous areas, with national explosion-proof certification.
▎Key Features ：
1.Auto-zero correction, peak detection, data hold, fast response, and quick zeroing.
2.High-capacity lithium battery with power detection and low-voltage warning.
3.Dual-sensor design for ppm-level trace detection and LEL-range measurement with auto-switching.
4.Segmented LCD display with auxiliary LED alarm thresholds (10ppm, 100ppm, 1000ppm, 1%vol).
5.Audible & visual alarms with manual mute; different alarm frequencies for varying conditions.
6.User-configurable password for operation security.
