INTRODUCTION
The D640 features a long life sensor technology that is designed to
detect H2/Nitrogen Tracer Gas mixture
The D640
’s unique digital leak size indicator takes the guesswork out
of whether or not 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.
The D640 does not require rechargeable batteries. When used with
the H2/Nitrogen Tracer Gas mixture, the D640 will detect leak rates
less than 5 ppm. This complies with standards EN35422 and
EN14624. The Tracer Gas mixture complies with Article 6,
Paragraph 3 of EU Directive 2006/40/EC.
