There are two measuring channels in the cell and cell head for external temperature checking.
1.2.4 The cell head
The cell head has its own thermostat that automatically adjusts itself to the cell temperature. It closes
the measurement cell upward and ensures that the syringes are preheated. Fine adjustment of the
temperature to optimize the temperature difference between the cell and cell head can be carried out
with a potentiometer on the rear Figure 1-2 (6). The temperature of the cell head should be about
0.5°C lower than the cell temperature. Temperatures can be checked with an external thermometer in
the corresponding measuring channels Figure 1-6: Measurement of the head/cell temperature. To
prevent temperature effects, the cell head has a cover that is fastened with a knurled screw.
