Preparing the determination of the temperature correction
The figure shows in detail how the accessory parts are to be assembled
for the determination of the temperature correction. Proceed as follows:
1 Preparing the reaction vessel cover
￭ Mount the air tube on the reaction vessel cover.
￭ Clamp the first spacer at a distance of approx. 12 cm from the
lower end onto the air tube.
￭ Clamp the second spacer at a distance of approx. 5 cm from the
lower end onto the air tube.
￭ Insert the temperature sensor from above into the temperature
sensor opening and fasten it in the corresponding openings of the
spacers.
2 Preparing the reaction vessel
￭ Fill the reaction vessel with 6 g silicone oil (6.2326.000).
￭ Place the reaction vessel cover with the temperature sensor on
the reaction vessel.
￭ Push the temperature sensor all the way down (the sensor must
touch the vessel base).
3 Inserting and connecting the reaction vessel
￭ Insert the reaction vessel with the mounted reaction vessel cover
in the measuring position 2 or 3 of the required heating block.
￭ Screw one end of the FEP tubing 250 mm to the M8/M6 thread
adapter of the reaction vessel cover.
￭ Screw the other end of the FEP tubing to the corresponding con-
nector of the 895 Professional PVC Thermomat.
￭ Connect the temperature sensor to the Pt100 connector (2-9) on
the rear of the 895 Professional PVC Thermomat.
