NA-1 Portable Hydrogen Leak Detector
Portable hydrogen leak detection with dual-sensor, dual-range measurement for maintenance inspection and industrial hydrogen safety applications.
Overview
The NA-1 is a handheld hydrogen leak detector designed for portable field inspection and maintenance work. It uses a dual-sensor detection mode to combine small-range high sensitivity with large-range high accuracy, making it suitable for both ppm-level trace leak checks and wider-range hydrogen leak measurement. It is well suited for hydrogen-cooled generators in power plants, hydrogen production stations, and hydrogen pipeline leak inspection where fast response and practical portability matter.
Key Applications

How It Fits Into a Complete Solution
The NA-1 can be used as part of a wider hydrogen safety solution together with fixed hydrogen sensors, gas analyzers, alarm systems, and process monitoring equipment. It is especially useful where portable inspection complements fixed monitoring or maintenance workflows. In hydrogen production, transfer, and power industry applications, it can serve as the front-line tool for on-site leak checking while fixed systems provide continuous monitoring.
