LACO Technologies
Ensure the associated Helium Leak Detector used with the Concentration tester is
maintained regularly by doing the following.
•
Perform internal calibration on all non-Alcatel Leak Detectors at least monthly
and preferably weekly.
•
Change backing pump oil regularly.
•
Ensure Leak Detector is serviced regularly, whether by LACO or in-house.
•
Ensure all connections are leak tight.
Items identified as critical spares typically have a high likelihood of needing
replacement so the Helium Concentration Tester can stay in proper operating
condition. Parts listed that are not critical spares may fail but are more unlikely to
than critical spares. Take special not of the replacement intervals in the table below as
it is always best to replace a component before it fails and leads to equipment
downtime.
