Viscometers, glass, kinematic, Ubbelohde

Instruments necessary for controlled accuracy, manufactured using the KPG process. Accuracy of internal capillary dia.: < &plusminus;0.01 mm. Capillary viscometers of similar types and similar capillary numbers have the same K constant. For accurate calculation of speed gradients. The viscosity v (mm²/sec or cSt) is calculated by multiplying the constant K by the running time t: v = K x t.
Ubbelohde. To ISO/DIS 3105. DIN 51562. BS 188. NF T 60 to 100.
Without documentation of the constants.
For manual and automatic relative measurements.
