Techno Tools D740 - Introduction to D740 Tracer Gas Leak Detector; Key Features of the D740 Leak Detector

INTRODUCTION
The D740 features a long life sensor technology that is designed to
detect H2/N2 5/95% Tracer Gas mixture, also known as “Forming
Gas”.
The instrument’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.
When used with the H2/N2 5/95%Tracer Gas mixture, the D740 will
detect leak rates equivalent to 4 g/year of R-134a in the “HI” setting
and 7 g/yr in the “NORM” setting while moving the probe at
3”/second. This complies with SAE Standard J2970 sections 7.2 and
7.3. Leak Testing with Tracer Gas is consistent with the teachings
from EUStandards EN35422, EN14624, Article 6, Paragraph 3 of EU
Directive 2006/40/EC and the EU F-gas rules.
