Imperial Nitrogen/Hydrogen Tracer Gas Leak Detector LD-920

LD-920 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.

The Imperial Nitrogen/Hydrogen Tracer Gas Leak Detector LD-920 will detect Nitrogen/ Hydrogen trace gas leaks less than 5 parts per million [ppm] or equivalent in R134a would be 2.0 grams per year leak rate.

The LD-920 detects the Hydrogen component of the Trace Gas and cannot be used with straight Nitrogen.

The tracer gas mixture consists of a non-toxic, non-flammable, environmentally friendly mixture of 5% Hydrogen and 95% Nitrogen. Trace Gas was developed to remove the need to add polluting refrigerants in the system when pressurising systems for leak detection. For this reason, it can be vented to the atmosphere at completion.

To use Trace Gas, charge it into your new or decanted system at a pressure of approx 500 Kpa [75 Psi]. As Hydrogen is lighter than air, always sniff for samples above your suspected leak area, welds or fittings. The maximum distance away from the sampling area is 9.5mm at a rate no faster than 75mm per second. Refer to the Operators Manual for further usage information.
