Fluid Viscosity Tester

Fluid viscometers determine viscosity by measuring the resistance of a fluid under a specific shear rate. Their function is to quantify the flow characteristics of fluids and are applied in quality control in industries such as coatings and inks. Common types include rotational and capillary viscometers, which are suitable for different viscosity ranges and fluid types, respectively.
Selection
When selecting, consider matching the fluid viscosity range with the instrument's measurement range. Sample characteristics such as volatility or corrosiveness determine material requirements. Temperature control accuracy affects result reliability. Ease of operation and data output methods should meet daily usage needs. Budget and maintenance costs should be aligned with the actual frequency of application.

The difference between a wire bar coater and a gap-type wet film applicator.
The wire-wound drawdown bar directly quantifies the coating through the gap between wires, making it suitable for thin coating preparation with high precision, particularly for low-viscosity fluids. In contrast, the gap-type wet film applicator indirectly controls film thickness through the groove depth, with the actual coating thickness significantly influenced by material properties, making it more suitable for high-viscosity coatings and thick film preparation.
Types and Selection of Paint Viscosity Cups
As a simple tool for measuring the liquid outflow time, the viscosity cup is mainly categorized into various types such as the Tu-4 cup, ISO cup, Ford cup, and Zahn cup, based on standards from different countries and regions. These cups differ in orifice size, capacity, and the types of fluids they are suitable for.
