Imperial LD920 Nitrogen / Hydrogen Trace Gas Leak Detector

Imperial leak detectors feature long-life heated sensor technology, designed for high sensitivity. The digital leak size indicator takes the guesswork out of whether or not to repair a small leak. The digital display is independent of the audio alarm and sensitivity level, allowing the precise pinpointing of the leak source. All models use standard alkaline batteries- rechargeable batteries not required.
This instrument will detect Nitrogen/Hydrogen tracer gas leak rates less than 5ppm. The Trace-A- Gas mixture complies with Article 6, Paragraph 3 of EU Directive 2006/40/EU.
