HOW THE PRODUCT WORKS
Portable dual-range hydrogen leak detection for field inspections
The NA-1⁺ Portable Hydrogen Leak Detector is a handheld instrument for locating hydrogen leaks during field inspections. Its dual-sensor design automatically switches between a trace-gas range of 0–1000 ppm and a higher range of 0.1–4% Vol, helping operators assess both low-level leaks and higher concentrations with one portable detector.
The instrument uses pump suction at a specified flow rate of 200 mL/min. It provides a digital reading, stores measurement parameters and triggers an alarm when the measured concentration reaches a preset limit. Typical applications include leak checks on hydrogen-cooled generators, hydrogen production stations and hydrogen transmission pipelines.
Field setup and safety review
Before requesting a quotation, share the expected concentration range, sampling access, site classification, application and operating conditions. The reference lists explosion-proof marking Ex ib IIC T3 Gb; confirm the instrument marking, certificate scope and suitability against the hazardous-area classification and local requirements for each project.
These checks help select a portable hydrogen leak detector for field inspection in industrial and energy applications.
Key product features
Pump-suction sampling
A specified sample flow of 200 mL/min supports active gas sampling during leak inspections.
Fast response and practical measurement tools
The reference specifies response below 2 seconds and includes automatic zero correction, peak detection, data hold and fast zero return.
Preset alarms and clear status indication
A segment LCD displays readings; threshold LEDs indicate 10 ppm, 100 ppm, 1000 ppm and 1% Vol. Sound and light alarms can be manually silenced.
Portable rechargeable operation
The lithium-ion battery includes charge-level detection and low-voltage prompts. The listed battery life is up to 6 hours.
Explosion-proof marking listed
The reference gives Ex ib IIC T3 Gb and describes Zone 1/2 applications; verify project approval and marking before use.
APPLICATIONS
