Glass Testing Machine Wide Range Viscosity Measurement Device High Temperature Atmosphere Type WRVM-313HA
WRVM-313HA
Extensive glass viscosity measurement in a high-temperature atmosphere.
This device measures viscosity in a vacuum, in a gas atmosphere, and at high temperatures. Viscosity measurement involves measuring the deformation speed of the sample and the shear rate; however, conventional sensor heads require detection rods and rotating shafts to be non-contact with the structure, which makes it impossible to achieve a complete seal, resulting in measurements being conducted in a flowing gas atmosphere. This device adopts an indentation, parallel plate, and rotational method, allowing for a smaller sample shape and a more compact measurement sensor section, making it possible to house the entire measurement mechanism, including the electric furnace, within a vacuum cell.

basic information
【Features】 ○ Due to the small sample volume, the furnace volume can also be small, resulting in low temperature errors. ○ Continuous and extensive measurements can be performed on the same sample using penetration, parallel plate, and rotational methods. (Viscosity measurement range: 10^11 to 10^3 Poise) ○ The electric furnace and viscosity measurement mechanism are housed within a vacuum chamber, allowing for measurements in a complete atmosphere. ● For more details, please contact us.

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.
