The process of calibrating a viscometer is fairly simple and a standardized fluid at a certain temperature is used. The Brookfield viscometer is then used to measure the fluid and any adjustments that are necessary to get the known value for the standard when the device performs the test.
One of the most common calibration standard fluids is water. Using distilled water is recommended because it lacks any additional electrons and is generally uniform each time it is measured out to exact measurements.
Water at 20 degrees Celsius (68 degrees Fahrenheit) has 1.002 milliPascals units of viscosity. It also has a kinematic viscosity of 1.0038 millimeters squared per second. When the water is measured through a viscometer, these are the values that should be achieved through running the standardized testing for calibration. Every viscometer is capable of calibration. Calibration can also be done mathematically when necessary.
