Rotating Spindle Viscometer
The Orton Model RSV Viscometer is designed to measure the viscosities of a molten glass at various temperatures according to the ASTM C-965 Procedure A.
The Model RSV is a rotating spindle viscometer using the constant angular velocity method to measure viscosities at specific temperatures in order to generate a curve of the visco-elastic behavior of a molten glass. This system can also be used for testing according to ASTM C-1276 and ISO 7884/2 guidelines.
