sample introduction techniques. The effect of these elements on measurement tolerance must be
considered when verifying the calibration of your Brookfield viscometer. Sample temperature
in all test circumstances is very important, and will also add an additional expanded tolerance
depending on the temperature control system and the calibration verification tests begin with the
standard viscometer spindles as detailed above. Once the calibration of the viscometer itself is
confirmed, the expanded tolerance of the measurement system may be determined using accessory
devices. In many cases this additional tolerance will be very minimal, but as a general statement,
the addition of +/- 1% of the range in use is reasonable for accessories.
