The equipment in the lab is very good for
what it was designed to do. It is also very
expensive. The CCFD costs about 00. The
closed cup flash-point tester costs about 00.
Take care of your equipment and it will last a
long time. Also, remember the equipment is only
as good as the people who use it.
We are now going to go step-by-step through
the operation and calibration of the equipment
used in the Aviation Fuels Lab.
First, you should understand that the CCFD
is a newer model of the AEL Mk III with an AEL
Mk I built in the same case and that the CCFD
gives the sediment reading by digital display.
The theory and operation of the CCFD are the
same as for the individual units.
With any of the units, for initial startup or
after moving them from one space to another,
you MUST allow adequate time for the unit to
reach the same temperature as the space in
which it is to be used. This is IMPORTANT so
any condensation that may form inside the
machines will not affect your readings.
