Product Usage:
The immersion Zahn cup viscosity cup is manufactured in accordance with the American Society for Testing and Materials (ASTM) D4212-93 standard, "Standard Test Method for Dip-Type Viscosity Cups." This viscosity cup is designed for measuring the viscosity of Newtonian or near-Newtonian liquids.
It is widely used in the coatings, ink, gravure, letterpress, lithographic, flexographic, and screen printing industries for viscosity measurement before or during application. It helps maintain consistent viscosity within the desired range to ensure product performance and quality.
The Zahn Cup is a commonly used tool for liquid viscosity measurement. The viscosity value obtained through this method is typically expressed in seconds and can be converted to centipoise using appropriate conversion methods.
Standard Test Method: ASTM D4212 - Dip-Type Viscosity Cups.
The test liquid should be maintained at a temperature of 25°C, with temperature fluctuations not exceeding ±0.2°C during testing.
To use:
- Select the appropriate cup number based on the expected viscosity range of the liquid.
- Fully immerse the cup into the test liquid.
- Measure and record the liquid temperature inside the cup using a thermometer, then remove the thermometer.
- Use the index finger to lift the cup vertically by the handle ring, quickly and steadily.
- Start the stopwatch as the cup leaves the liquid surface. Maintain the cup no more than 15 cm above the liquid level during drainage.
- Stop timing at the moment the steady stream of liquid first breaks.
Maintenance:
With proper care, the Zahn Cup can last for many years. Clean with a soft cloth only—do not use wire brushes, sandpaper, or other abrasive materials. It is essential to clean the orifice carefully to remove residue and avoid scratching the internal surfaces. It is recommended to clean the cup after each use, except during repeated testing.
