Rheograph 20
Rheograph 20 is a high developed instrument especially for entry-level model user in the field of viscosity measurements. Additional modular based add-ons enable an extra value for determination of further material specific characteristics. The RG20 is working with a measurement force of 20kN. Besides the determination of viscosity, the Rheograph 20 is able to access the GÖTTFERT platform for extended material
characterization with the following features:
- PVT (Pressure, Volume, Temperature)
- Elongation (Haul-Off, Rheotens)
- Contifeed
- Shark-Skin
- Thermal Conductivity
- Counter-Pressure-Chamber
- Die Swell Measurement
