9. The power supply is two AA (No.5) batteries, which can work continuously for more than 150 hours (without backlight), and has power-saving functions such as automatic hibernation and automatic shutdown;
10, adopts the internationally popular fully enclosed aluminum alloy shell, which is ergonomically designed. The surface is sandblasted and equipped with stainless steel wire drawing baffle, which is corrosion resistant, beautiful and durable. And has excellent anti-electromagnetic and anti-vibration interference capabilities.
Applicable field:
In field work, bending specimens are often encountered, and various curved surfaces have different effects on the hardness test results. Under the correct operation, the instantaneous position of the impact on the surface of the specimen is the same as that of the flat specimen, so the universal support ring can be used. However, when the curvature is small to a certain size, the rebound speed of the impact body will be low because of the significant difference in elastic state of deformation under plane conditions, thus making the Richter hardness lower. Therefore, for samples, it is recommended to use a small support ring when measuring. For samples with small radius of curvature, it is suggested to choose special-shaped support ring.
Scope of application:
According to the principle of Richter scale hardness, as long as the material has certain rigidity and can rebound, the exact Richter scale hardness can be measured, but there is no corresponding conversion relationship between the Richter scale hardness of many materials and the hardness of other systems. The Richter hardness tester only contains conversion tables of nine materials. The specific materials are as follows: steel and cast steel, alloy tool steel, gray cast iron, ductile iron, cast aluminum alloy, copper-zinc alloy, copper-tin alloy, pure copper and stainless copper.
For some samples of special materials, users can use the fitting curve software provided by the company to make special conversion tables. In actual production, there are many kinds of metal materials used. Because the Richter hardness tester is sensitive to the processing mode of materials and the composition of alloy elements, the hardness conversion table stored in the Richter hardness tester chip can not meet the needs of users. Users can use fitting software to make their own special hardness conversion table during testing.
