Overview

The TOKI SANGYO TVC-5 is a portable, battery-operated rotational viscometer designed for quick, simple, and reliable on-the-spot viscosity measurements. Its “Handy Type” design emphasizes ease of use, portability, and durability, making it an ideal tool for quality control in fields like paints, inks, adhesives, cosmetics, food, and coatings—anywhere a rapid viscosity check is needed outside the lab.

Key Features

• Ultra-Portable & Handheld: Compact, lightweight design for easy one-handed operation and transport to any location—production lines, storage tanks, or field sites.

• Simple Operation: No complex setups or calibrations required for relative viscosity checks. Just immerse the rotor, press the button, and read the value.

• Battery-Powered (DC Operation): Powered by a single 9V battery (typically), ensuring complete portability and safety in various environments without the need for a power outlet.

• Robust 1.5W DC Motor: Provides consistent torque for measurements. The Serial Number 3371A indicates a specific unit from a proven production line.

• Multiple Rotor Options: Comes with a set of interchangeable rotors (e.g., standard RV-series style) to cover a wide range of viscosities, from low-viscosity fluids to pastes.

• Analog Needle Meter: Features a clear, easy-to-read dial display that indicates viscosity. The meter typically shows values in centipoise (cP) or arbitrary units, with a multiplier based on the rotor and speed used.

• Rotational Speed Selection: Offers multiple fixed rotational speeds (e.g., 6, 12, 30, 60 RPM) to simulate different shear conditions and optimize measurement for various fluids.

• Guard Leg & Stand: Includes a protective guard leg for stability during measurement and often comes with a simple stand for bench-top use.

Typical Specifications

• Measurement Principle: Rotational viscometry (single cylinder in infinite sea).

• Viscosity Range: Dependent on rotor and speed combination. Can typically measure from ~10 cP up to 130,000 cP or more with the appropriate rotor.

• Speeds: 4-5 fixed speeds (e.g., 6, 12, 30, 60 RPM).

• Display: Analog meter (dial gauge).

• Power Supply: 1 x 9V battery (or similar, depending on age/model variant).

• Dimensions & Weight: Highly compact, approximately ~300mm tall and weighing under 1 kg.

Common Applications

• Quality Assurance (QA): Fast batch-to-batch consistency checks.

• Production Control: Monitoring viscosity during manufacturing processes.

• Field Service: Checking the viscosity of oils, gels, or mixed materials on-site.

• Educational Demonstrations: Teaching basic rheological principles.
