Glass testing machine Glass parallel plate viscosity measurement device PPVM-1100/1350
PPVM-1100 / 1350
Quality control of glass adhesives and viscosity measurement in the working temperature range.
In conventional glass viscosity measurements, the range of 10^4 Pa.s (10^5 poise) is difficult to measure with rotational methods, and the sample preparation for the softening point measurement method according to JIS-R3103-1 was not easy. This glass viscometer is a device that continuously measures from 10^3 to 10^8 Pa.s (10^4 to 10^9 poise) using the parallel plate measurement method, which heats and applies pressure to samples with parallel surfaces.

Company information
Under recent high technology, the measurement of viscosity in the glass and ceramics field, which was considered unremarkable, has become a particular focus in fundamental research. Here, I would like to introduce various devices, primarily focusing on viscosity measurement, including glass testing machines, strain testers, electrical conductivity measurement devices, and loss of transparency testing equipment.
