With the MonTech upgrade program, the Alpha Technologies MDR 2000 is completely revamped to reflect modern technological needs while achieving better accuracy and repeatability. The Alpha MDR, also known as the Monsanto Moving Die Rheometer in the 2000 series, is facing challenges of aging. Nearly 75 changes are made to the MDR 2000 to bring it to life again at the fraction of the cost of a new moving die rheometer.
