Material Testing Instruments

N-1517 Airflow Resistance Measurement System

Typical applications are for quality control for sound absorption and for filter production process, and testing in research & development. Various adapters allow differently sized test material to be measured. The results are obtained quickly, with no need for external air hook-up. A large dynamic range allows many different samples tested with no adjustment needed.

Viscotester VT-03F/04F

This product is designed for a wide range of viscosity measurements. It is suitable for checking industrial substances such as heavy oil, paint, and adhesives. It can be used for quality control in manufacturing processes of foodstuffs and other products. When inspecting construction vehicles and other machinery, the unit can serve to measure not only the viscosity of hydraulic oil but also of light spindle oil, gear oil, etc.

The unit employs the rotating cylinder principle. A rotor turning at constant speed is inserted into the liquid to be measured. The resistance to rotor movement caused by the viscosity (torque) is measured using a special mechanism to obtain direct readings in millipascal-seconds (mPa.s) or decipascal-seconds (dPa.s).
