RMS 7200



RMS-7200, a strain control rheometer, was modified by replacing the original motor with a digitally controlled servomotor. This rheometer has the original load cell with the maximum torque response of 2N.m (20, and maximum normal force response of 20N (2,000g).


Experimental application

1. Investigation of nonlinear viscoelastic properties of branched polyethylene

2. Normal force responses in polymer glasses
