Equipment Overview
This is a device for measuring the viscosity of glass in the strain point and slow cooling point regions, and complies with ISO 7884/4 and 7884/7 by employing the beam bending method, which is specified in the JIS standard “JIS R-3103-2, Method for measuring slow cooling point and strain point by fiber stretching method.
Features
- Automatic operation and data processing by PC.
- The measuring fixture is made of fused fused silica glass, and errors due to thermal expansion are compensated for by data processing software.
- Displacement is read under constant load by a servo mechanism.
