Digital display electronic ink viscosity meter

A Digital Display Electronic Ink Viscosity Meter is a laboratory or production instrument designed to measure the viscosity (thickness or flow resistance) of inks, paints, coatings, and similar fluids.

How it works

The working principle of the digital display electronic ink viscosity meter is based on two tin (usually a metal roller and a rubber roller) rotating under a given pressure, speed and temperature conditions, by measuring the separation force of the ink film between the rollers to assess the viscosity of the ink. When the roller rotates, the ink film coated on it is subjected to shear force and separated, at this time the instrument records the force required to separate the ink film, thereby calculating the viscosity value of the ink.

Application field

Digital display electronic ink viscosity meter is widely used in printing, packaging, ink manufacturing and other industries to measure the viscosity value of various types of ink to ensure the quality and stability of printed matter. In addition, the instrument can also be used in ink research and development, quality control and product inspection.

Technical parameters

The technical parameters of digital display electronic ink viscosity meter may vary from model to model and manufacturer, but usually include the following aspects:

Copper roller spindle speed: multi-speed adjustable, such as 400 RPM, 800 RPM, 1200 RPM, 1600 RPM or 2000 RPM, to adapt to different test needs.

Total electrical power: Usually between 1500 watts and 1600 watts, depending on the configuration and manufacturer of the instrument.

Pump flow rate: for the circulating water of the thermostatic water tank, the flow rate is generally greater than or equal to 10 liters/min to ensure the stability of the test environment.

Thermostatic water tank capacity: generally 6 to 8 liters, used to maintain a constant temperature during the test.

Display accuracy: usually 0.1 ink viscosity unit, to ensure the accuracy of measurement results,

Test accuracy: under the same test conditions, the retest error is generally controlled within +0.3 to +0.5 ink viscosity units.

Spindle level error: After the table is leveled, the spindle copper roller level error is usually controlled within 0.03 mm.

Thermostatic water tank temperature adjustment error: the temperature adjustment error of a single thermostatic water tank is generally less than or equal to 0.5 °C, and the temperature adjustment error of a dual-purpose thermostatic water tank may be smaller, such as less than or equal to 0.19°C
