Pendulum Hardness Tester

Pendulum Hardness Tester

A pendulum resting on a coating surface is set into oscillation and the time for the oscillation amplitude to decrease by an amount specified in this International Standard is measured. The shorter the damping time, the lower the hardness.
Two test procedures are considered in some detail, namely those of König and Persoz.(The Persoz and König methods differ by the period and amplitude of the oscillation. The Persoz test measures the time taken for the amplitude of oscillation to decrease from 12° to 4°; the König from 6° to 3°.)

The instruments embody the same principle — that the amplitude of oscillation of a pendulum touching a surface decreases more rapidly the softer the surface — but differ in respect of dimensions, period and amplitude of oscillation.

BGD 509/S Pendulum Hardness Tester is the newest product which can be used in accordance with the following National and International Standards: ISO 1522, ASTM D4366,BS 3900-E5,DIN 53157,NBN T22-105,NF T30-016.
It’s a simple to use instrument and can be supplied in one of three model types: Persoz, König, and Persoz and König combined

BGD 746 Super High Speed Dispersing Machine integrates super high-speed dispersion, stirring and automatic control of lift distance. It can meet the application requirements of customers for super high-speed dispersion and homogeneous emulsification, with the excellent dispersion and emulsification effects, as well as high dispersing efficiency. In addition, this machine is operated by a large-size touch screen, which is powerful, convenient and practical. Features ◆ Super high-speed motor: The max. speed can reach 20,000 r/min. Bigger torque, lower noise and lower power consumption. ◆ The max. lift distance can reach 300mm. Servo system for locating can precisely feedback the height information in real time. ◆ Dispersing blade can be set to stay at the required height, which is suited to different sizes of dispersing containers or different material levels. At the same time, the use safety can be improved. ◆ In the whole dispersing process, the dispersing blade can stir circularly between the set upper and lower limit. The lift distance and speed can also be set. Greatly improve the dispersion efficiency. ◆ With the 7-inch touch screen, the tip speed, torque ratio and the height of dispersing blade can be displayed in real time. ◆ Test parameters can be set, such as speed, run time, diameter, height, etc. ◆ Suitable for containers with the capacity of 0.5L-5L, and can meet more different test requirements.
