- Abstract:
- This paper describes a new type of Buchholz Indentation Hardness Tester used in Buchholz Indentation test for paint and varnishes. This new type tester uses a bridge structure to connect two cantilever sensors together, so we can instantly know the magnitude of the acting load on paint and varnishes. The design overcomes the defects of the previous load changes that could not be accurately predicted. At the same time we can use the adjustment hole to accurately adjust the level of the hardness tester, to ensure the standardization of the measurement process. By evaluating the uncertainty of the measurement results, the newly designed hardness tester ensures the accuracy and reliability of measurement results.
