VT-06 | Viscometer
History of RION Viscotesters1957: First vibration viscometer V-1201 developed. 1960: Viscotester V-1207 developed and released to the market. 1965: VT-01 for normal viscosity and VT-02 for high viscosity released. Subsequent developments include the further improved models VT-03/VT-04 and VT-03F/04F. 2013: The Viscotester VT-06 with LCD panel is released. This model continues to be available today. |
VT-06The VT-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.

Rotor extension The supplied foldable rotor extension consists of three 30 cm rods joined by rings. The combined length is 90 cm. When wishing to use the extension at a length of 30 cm or 60 cm, open the connector rings with a pair of pliers, remove the desired number of elements, and rejoin the extension rods. Be sure to close the rings fully again, to prevent the extension from getting detached during use. Attach the end with the male thread to the viscotester and the end with the female thread to the rotor. Note that both are left-hand (reverse) screw threads, so you must turn the parts counterclockwise to screw them in. When measuring a fluid with high viscosity, the joint will look as shown in the illustration, but this does not affect the measurement. The rotor extension rods are made of stainless steel. |

* About power swing
When the rotor starts to turn, temporary overload may cause a socalled power swing condition where the rotor cannot turn properly. In such a case, the indication “FAIL” is shown on the display, the rotor is stopped, and then started up again.
