Devices for liquid material testing

In the realm of coatings and liquid materials, understanding and controlling viscosity is paramount. Viscosity, the measure of a fluid's resistance to flow, directly influences application properties, drying times, and the overall quality of the final product. To ensure optimal performance and consistency, precise viscosity measurement is essential. NOVOTEST offers a comprehensive range of instruments designed to assess the viscosity and related properties of liquid materials, catering to various industrial needs.

Importance of Viscosity Measurement

Viscosity impacts several critical aspects of coatings and liquid materials:

• Application Efficiency: Proper viscosity ensures that coatings are applied uniformly, reducing defects such as sagging or running.
• Performance Characteristics: The right viscosity contributes to desired film thickness, adhesion, and durability of the coating.
• Process Optimization: Monitoring viscosity aids in maintaining consistency during production, leading to reduced waste and improved quality control.

Given these factors, accurate viscosity measurement is indispensable in industries like automotive, aerospace, construction, and manufacturing.

NOVOTEST Viscosity Measurement Instruments

NOVOTEST provides a suite of instruments tailored for evaluating the viscosity and related properties of liquid materials:

Viscosity Flow Cup NOVOTEST VZ-246

The Viscosity Flow Cup NOVOTEST VZ-246 is designed to determine the conditional viscosity of Newtonian fluids. This device is essential for assessing materials such as paints, varnishes, and other industrial liquids. Key features include:

• Design: A cylindrical reservoir transitioning into a cone with interchangeable nozzles of diameters 2 mm, 4 mm, and 6 mm.
• Measurement Range: Capable of measuring outflow times from 12 to 300 seconds, depending on the nozzle used.
• Applications: Suitable for both laboratory and production environments, ensuring consistent product quality across batches.

Submersible Viscosity Flow Cup NOVOTEST VZ-246P

For rapid testing of large batches or hot liquids, the Submersible Viscosity Flow Cup NOVOTEST VZ-246P is ideal. This instrument allows for quick assessments directly within production environments, making it invaluable for real-time quality control.

Viscosity Dip Mug NOVOTEST VMS

The Viscosity Dip Mug NOVOTEST VMS is a cylindrical brass vessel designed to determine the conventional viscosity of coarse dispersion polyvinyl-acetate homopolymers. It features a handle and three orifices—two on the lateral wall for manual use and one at the center of the base—facilitating versatile application in various testing scenarios.

Density Cup NOVOTEST PYCNOMETER P-2811

Density measurement is closely related to viscosity in characterizing liquid materials. The Density Cup NOVOTEST PYCNOMETER P-2811 determines the density by measuring the mass of a liquid in a container of known volume at a specific temperature. This data is crucial for calculating other properties and ensuring material consistency.

Film Applicator NOVOTEST AU-1

Consistent film thickness is vital for accurate viscosity measurements. The Film Applicator NOVOTEST AU-1 allows for precise application of coatings with adjustable gap heights between 10-6000 µm. This ensures uniform layers, essential for subsequent testing and quality assessments.

Grindometer NOVOTEST GD-1

Particle size and dispersion quality can influence a liquid's viscosity. The Grindometer NOVOTEST GD-1 measures the fineness of grind of coatings, inks, and other liquid materials. Understanding particle size distribution helps in correlating viscosity with material composition and processing parameters.
