Brookfield recommends that all fluids be replaced annually. In order to check the calibration of your instrument, a Constant Temperature Water Bath may be required.
Brookfield Viscosity Standards provide a convenient, reliable way to verify the calibration of your Brookfield Laboratory Viscometer/Rheometer. Brookfield Viscosity Standards are Newtonian, and they are available as either silicone or oil. Silicone fluids are less temperature sensitive than oil fluids.
