INTRODUCTION
The LD920 features a long life sensor technology that is designed to detect H2/N2
Tracer Gas mixture.
Our unique digital leak size indicator takes the guesswork out of whether to repair
a small leak. The digital display is independent from the audio alarm and sensitivity
level, allowing the precise pinpointing of the leak source.
When used with the H2/N2 Tracer Gas mixture, the LD920 will detect leak rates
less than 5 ppm. The 5%H2/ 95%N2 Tracer Gas mixture is consistent with the
teaching of EMC Directive 2014/30/EU for use with Low GWP Leak Detection
System Tracer Gas. The LD920 does not require rechargeable batteries.
