The heat sink block, when used with the high
temperature thermal barrier, both supplied
with the Elcometer 215 Model T and available
to purchase as accessories - see Section 3.8
‘The Thermal Barrier & Heat Sink Block’ on
page en-7 - enables the logger to be used at
elevated temperatures over a longer time
period, see ‘Thermal Characteristics’ table on
page en-7 for further information.
The heat sink material absorbs large amounts of heat energy and
consequently, it has a relatively low melting point. The material
changes phase from a solid to a liquid when the temperature of the
heat sink is above 32°C (89.6°F). The heat sink should therefore be
kept cool before use in order to maximise the protection it provides the
logger.
Ideally, the heat sink should be at 20°C to 22°C (68°F to 71.6°F)
before use. In warm ambient temperatures above 25°C (75°F), it is
recommended that the heat sink is cooled / chilled before use. A
possible solution is a refrigerator at 7°C (44.6°F). Re-crystallisation
(change from liquid to solid) will start between 24°C and 26°C (75.2°F
to 78.8°F); cooling in a freezer or ice bath / cool water bath will speed
up this process.
