For measurements at different temperatures, the CT 72/2, CT 72/4 transparent thermostats are available.
These thermostats can be equipped with two or four viscometers including other equipment. For
measurements up to 60 °C, the thermostat CT 72/P of acrylic can be used.
The bath body of the thermostat CT 72/P consists of acrylic (PMMA)! Acrylic can be damaged by a
variety of organic solvents as well as by concentrated acids/bases. Therefore, a contact of the bath body
with such substances should be avoided, as the acrylic may be damaged.
Please read the separate operating manual of the transparent thermostats as well.
Flow coolers
2.3.5
As was mentioned above, viscosity measurement is highly dependent on temperature
constancy. For reasons of control technology (self heating of the thermostat head), it is therefore necessary
to use a CK 300/CK 310 flow cooler as a counter cooler at bath temperatures exceeding 40°C.
Please read the separate operating manual of the flow coolers as well.
ViscoPump III module
2.3.6
The ViscoPump III modules control the entire measurement process, among other things the temperature
pre-adaptation process of the samples in the viscometers, the process of pumping the liquid up into the
storage containers of the viscometers, the measurement of the flow times etc.
To replace the ViscoPump III module, please proceed as follows:
Switch off the AVS
Remove the pneumatic and electrical connections from the front panel of the ViscoPump III module
to be replaced.
Loosen the screws located at the corners of the front panel.
Use the upper and lower insertion handles to leverage the ViscoPump III module out of its rearside
plug connection.
Pull the ViscoPump III module out of the AVS
After inserting the new ViscoPump III module, please secure it again with the screws of the front
panel. Re-establish the electrical and pneumatic connections.
Insert the mains plug into the socket and switch on the AVS
After connecting, check whether the correct operating mode, "Suctioning" or "Pushing" is visibly set on
the corresponding LED on the front panel. Changing the operating mode to the application is described in
section 4.6, Figure 23. Use the hose fittings designed for this purpose!
