Lack point
* require the sample to have a wide flat surface. So it is not easy to test the narrow strip, the small size sample and the curved surface sample.
* Hardness Conversion error. In test aluminium profiles to Barcol hardness conversion into webster hardness, and Barcol hardness conversion tables and national nonferrous standard YS/T420- 2000 conversion table 2.7 webster hardness unit difference. Therefore, the conversion table of the hardness tester should be used with caution.
* there is a defect in the PAP hardness block. Barcol hardness block thickness only 0.8mm, after testing, hardness blocks back will produce visible deformation traces, which shows insufficient hardness block thickness, this violates the indentation hardness specimen thickness on the basic principle, will bring the big test error.
* lack of good after-sales service. Equipment manufacturer in the country without a point of repair, each Proxy Companies as a trading company are lack of maintenance capacity. Therefore, the use of the hardness tester in the equipment maintenance and spare parts supply will be difficult.
The company as a portable hardness tester of the production plant, the hardness of the hardness tester has more research, has been repaired hundreds of 934-1 type instrument, can provide a spot of hardness and Pap hardness of the needle, providing one year warranty period. If it does require the use of the hardness tester, it is a wise choice to purchase from the company.
