7. Measurement accuracy of +/- 5% F.S
8. Dedicated Power Adapter, Input Voltage Range 100~ 240V, Frequency 50~ 60Hz
Principle
The digital Rotational Viscometer is based on the principle of swirl/spin viscosity measurement. The rotor is driven by a motor to swirl/spin in the liquid. Tack resistance is measured when the rotor swirl/spin, which is detected by the Sensor and converted into an electrical signal. The viscosity value and related parameters are displayed in digital form after processing by the microprocessor.
Steps
1. Select the appropriate rotor and install it on the Viscometer
2. Immerse the rotor in the liquid to be tested to the designated marking position
3. Select the desired Rotation speed (6/12/30/60rpm)
4. Start the measurement and wait for the reading to stabilize
5. Read and record the displayed viscosity values and related parameters
6. Turn off the power after measurement and clean the rotor
