Temperature control
Value is stored
Value is stored
The temperature that is set on the device relates to
the thermal radiation that hits the sample to be dried.
The thermal radiation is an electromagnetic wave for
the transmission of energy. As this energy creates heat in the sample, the moisture evaporates from the
sample. The temperature is used to set the energy that allows the moisture to evaporates from the material
(more temperature is more energy).
The set temperature is not to be equated with the temperature to which the material or the environment heats
up.- The material or ambient temperature is a consequence of the drying process, not the cause of the drying.
Automatic shut-off or timer
The automatic mode dries the sample until a constant weight is reached and then switches off the heater.
The following settings
can be defined here:
1. Weight loss in mg
a value should be defined here which corresponds to approx. 0.1 % of the original sample e.g. original
sample 10 g = 10 mg
When the weight loss <= the mg weight specified here within the interval period defined below, the
measurement is completed, if at least the start of query time limit has expired.
2.
Query interval in secs.
an interval should be selected here, so that the sample is not dried for too short a period but also not for
far too long. A period of 20 to 30 secs is normally adequate. None /10-99 secs can be selected.
