6.3 TBHS-1 Heatsink User Information
Please Note:
The heatsink material is developed to absorb large amounts of heat energy, as a result of this it has
a relatively low melting point.
So it is essential the heatsink should not be used if the heatsink material is in liquid form.
The material will change phase from a solid to a liquid when the temperature of the heatsink is above
32°C.
Therefore the heatsinks are required to be kept cool to ensure they offer the maximum protection
before use. Ideally they should be at 20 - 22°C. In warm ambient temperatures i.e. above 25°C then
it is recommended that the heatsink be cooled/chilled prior to use. A possible solution is a
refrigerator at 7°C) . Failure to cool the barrier between use will result in the logger being permanent-
ly damaged.
Re-crystallisation (change from liquid to solid) will start between 24 and 26°C; cooling in a freezer or
ice bath / cool water bath will speed up this process.
Hazardous Information:
