Rheograph 20
The Rheograph 20 is the basic model equipment for measuring viscosity which comes
with a working force of 20kN.
It has additional modules to add on to determine further characteristics of
different applications and materials.
PVT (Pressure, Volume, Temperature)
Elongation (Haul-Off, Rheotens)
Contifeed
Shark-Skin
Thermal Conductivity
Counter-Pressure-Chamber
Die Swell Measurement
20 kN test force and a dynamic speed range from 0.0001 mm/s (0.006
mm/min) – 30 mm/s (2400mm/min)
Single or twin barrel system in 9.55, 12, 15 or 20 mm design
Temperature control range up to 400°C (500°C optional), display
resolution 0.01°C
High temperature stability and extremely low deviation over the whole
test barrel length as well as in the die area (norm and standard
overmatching)
Automatic pressure transducer detection and identifying („Plug / Test“)
Adaptive signal resolution of only 0.005% from the pressure transducer
range
