Ready-to-use viscometry standards verify that laboratory rhemoeters, viscometers, and other related measuring equipment possess a reliable calibration at all times. Using mediums with known thickness levels, accurate comparisons can be made in maintenance inspections to guarantee the apparatus performance remains consistent. Offering the highest sensitivity, oil solutions are typically designed for specific equipment designs. Popular for addressing general purpose applications, silicone fluid viscometry standards have excellent temperature stability for when levels can only be minimally controlled.
