In order to obtain correct measurement results from testswith a rotational rheometer, it is of upmost importancethat the sample temperature is adjusted correctly. Thetemperature reading displayed in the Thermo ScientificTM
HAAKETM RheoWinTM software represents the temperatureof a temperature sensor inside the temperature controlmodule. Depending on the individual measurement con-ditions, the actual sample temperature can differ signi-ficantly from this reading. Conditions that affect theoffset between instrument reading and actual sampletemperature include:
••••• the difference between test temperature and ambienttemperature
••••• the applied measuring geometry••••• the utilization of a sample cover
It is therefore strongly recommended to determine thetemperature offset between temperature reading andsample temperature.
Depending on the temperature range and the numberof temperature steps, this calibration can be very timeconsuming. With the optional temp offset tool, thetemperature calibration runs automatically without userintervention during the run.
The temp offset tool consists of a digital thermometerand an add-on module for the HAAKE RheoWin software.Depending on the type of measuring geometries used,a thin thermocouple for concentric cylinder geometriesor a thicker thermocouple for parallel plate geometriesis available (Fig.1 and Fig. 2).
The digital thermometer connects to the computer via an USB port and can be used by HAAKE RheoWin software afterwards. The user enters the range of temperature, the number of steps to divide it into and the precision needed. With this input, the calibration can be started and will run unattended (Fig. 3).

It is important to use the same configuration of therheometer during temperature calibration that will after-wards be used for the sample measurement. This includ-es the temperature control unit, measuring geometryand sample cover, if used.
After the calibration run has finished, the temperaturecan go to a user-defined temperature, for example thestart temperature of the next rheological measurement.
The temp offset tool can be used with theThermo ScientificTM HAAKETM ViscotesterTM iQ, the Thermo ScientificTM HAAKETM RheoStressTM 600(0) and the Thermo ScientificTM HAAKETM MARSTM rheometers using their own temperature controller or a HAAKE SC or AC circulator.
