Double-Pendulum Method Hardness Tester

The double pendulum hardness tester measures the hardness value by calculating the swing decay time of two pendulums with different masses oscillating on the coating surface. It is used to evaluate the surface deformation resistance of materials such as coatings and plastics, and to monitor the degree of coating curing in quality control and research and development.
Selection
When selecting, focus on ensuring the measurement range matches the sample hardness, the pendulum type meets standard requirements, calibration functions guarantee data accuracy, the operation interface is simple and easy to read, environmental temperature fluctuations must remain within the allowable range, and the sample stage must be stable and vibration-resistant.
