Fitting AutoDest sensor and vapor temperature sensor (optional
accessory)
When using an Interface I-300/I-300 Pro there is the option of performing automatic
distillation. Automatic distillation requires connection of an AutoDest sensor to the
Rotavapor R-300. The AutoDest sensor is connected to the inlet and outlet of the
cooling condenser and continuously measures the following temperatures:
Temperature of the incoming coolant
Temperature of the outgoing coolant
Temperature of the vapor exiting the evaporating flask
NOTE
The AutoDest sensor has to be calibrated when first used and also when connected
to a new VacuBox (see Operating Instructions I-300/I-300 Pro, Section 8.5 "Calibrat-
ing AutoDest sensor").

NOTE
There are two arrows stamped on the AutoDest sensor indicating the direction of flow
for the coolant. The hoses for the coolant must be connected according to the direc-
tion of flow as the AutoDest sensor measures the difference between the incoming
and outgoing coolant temperature and communicates the readings to the VacuBox
and interface unit for the purposes of automatic control.
