DV Rotational Viscometer is a commonly used viscosity testing instrument, which can be used to measure the viscosity of various liquids, including paints, coatings, colloids, cosmetics, food, etc. When choosing a DV Rotational Viscometer, the following points and precautions need to be considered:
select points
Measuring range: Different DV Rotational Viscometers have different measuring ranges, and the appropriate range needs to be selected according to actual needs. In general, the selected range should be 1 to 2 orders of magnitude larger than the viscosity of the liquid to be tested.
Measurement accuracy: The accuracy of the viscometer is usually between 1% and 5% of the measurement range, so it is necessary to select the appropriate accuracy requirements according to actual needs.
Rotor model: DV Rotational Viscometers are usually equipped with different types of rotors, which are suitable for different types of liquids, and it is necessary to select the appropriate rotor model according to actual needs.
Measuring speed: Different viscometers have different measuring speeds, and the appropriate speed should be selected according to actual needs.
Precautions
Operating specifications: Before using the viscometer, you need to be familiar with the operating instructions of the viscometer and follow the operating specifications of the viscometer.
Calibration: Regularly calibrate the viscometer to ensure the accuracy and reliability of the measurement results.
Cleaning: The sensor and rotor of the viscometer should be cleaned regularly to avoid dust and dirt from affecting the measurement results.
Maintenance: Regularly maintain and maintain the viscometer to ensure its normal operation and service life.
In short, the selection of DV Rotational Viscometer needs to consider the actual needs, and select and use according to the main points and precautions.
