AC 7490
ELECTRONIC LEAK DETECTOR FOR NITRO-TRACE TESTING (N2-H2)
INTRODUCTION
CHARACTERISTICS
The AC 7490 features a long life sensor technology that is designed to detect H2/nitrogen tracer gas mixture
The AC 7490’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 AC 7490 does not require rechargeable batteries. When used with the H2/nitrogen tracer gas mixture,
The AC 7490 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.
