calibrated leaks
Principle
external calibrated leak
recalibration
There are several types of calibrated
leaks, with or without reservoir, with
or without valve, covering several leak
ranges. The choice of the appropriate
external calibrated leak depends on the
application requirements.
For further information on the Adixen
calibrated leaks, please refer to our
product catalog or consult your local
A.V.T.F. sales engineer.
Most of the Adixen calibrated leaks are
delivered with a calibration certificate.
The manufacturer does not supply the calibrated leaks in Helium 3
and Hydrogen.
All Adixen calibrated leaks are based on permeable membrane
technology.
Most calibrated leaks last many years even though the helium is
permanently escaping (the leak rate is very small in comparison to the
amount of helium contained in the reservoir: yearly loss is indicated
on the calibrated leak identification label).
However, it is recommended to have every calibrated leak (with
reservoir) recalibrated on regular intervals to validate its value: this is
applicable for both internal and external calibrated leaks.
Recalibration period of the calibrated leak depends on its leak rate
value.
Recommendation for proper Quality Control:
THE RECALIBRATION INTERVALS SHOULD NOT EXCEED 2 YEARS.
Please consult your local Alcatel Sales representative for additionnal
information.
