Rotorless Rheometer

model RLR-4

The TOYOSEIKI Rotorless Rheometer model RLR-4 measures vulcanizing characteristics of rubber with ease and simplicity at high accuracy. It allows labor saving in conducting test by installing the pin type automatic sample loading/unloading device of high reliability and high reputation and data processing unit as option.

Moreover, it allows you to determine more physical characteristics of rubber by installing the optional foaming pressure measuring function and tanδ measuring function.
