VT-05/06, Uni-Cylinder Rotational Viscotesters
The VT-05/06 is designed for quality control applications in the
manufacturing process of industrial products such as petrochemicals, paint,
and adhesives, as well as foodstuffs. Viscosity measurements covering a
wide range are possible, such as gear oil used in construction machinery.
Measurement is performed by simply submerging a rotor in the fluid. The
resistance to rotor movement caused by the viscosity (torque) is measured
to obtain direct readings.
1. Attach rotor to unit and hold unit in the hand or place on dedicated
stand. (Unit should be approximately horizontal in either case.)
2. Insert rotor in sample fluid, turn power on, and select rotor number.
3. Press start button and read indicated viscosity.
*
VT-06 allows use of No. 1 rotor, No. 2 rotor. and supplied extension rod to
reach fluid at a greater distance.
