ABOUT US
Measuring what really matters since the late 1990’ies
In response to an industry demand for automation of capillary viscometry, the first PSL Rheotek polymer viscometer systems were supplied in the late 1990’ies. The viscometer offered clients the confidence of well proven protocols as detailed in international standards, while limiting operator exposure to chemicals and providing an improvement in the repeatability of test results.
