A comprehensive range of calibrated precision glass capillary kinematic viscometers for both manual and automated use. These instruments are used in laboratories across the world and enjoy a high reputation for quality of workmanship and accuracy of calibration.
PSL viscometers are constructed from low-expansion borosilicate glass and the precision bore tubing used for the capillary section is held to a close tolerance of ±0.01mm.
The PSL Calibration Laboratory maintains its own primary viscosity scale, based upon the internationally agreed value of distilled water at 20°C of 1.0034mm²/s. Each calibration performed is one step away from this primary scale, producing very low uncertainties of measurement.
