首先，我們需要了解我們需要檢測的工件的規(guī)格以及工件的尺寸、厚度、表面粗糙度等物理性能。 工件的材質也會對測試結果產生不同的影響，如鋁、銅、工具鋼等特殊材質，不同材質的回彈模量不同，沖量裝置的選擇極為重要 為測試結果。

  購買里氏硬度計的目的是需要測試的硬度值，HL、HB、HRC、HRB、HV、HS。 如果您滿足以上條件，就可以購買一臺硬度計，可以提高您的工作效率。 硬度計可以在一個屏幕上同時顯示以上6個單位的硬度值。

  真正的里氏硬度計符合國家和國際標準并且可以互換。 雖然國內有關部門制定了里氏硬度計標準，但一些廠家有技術實力生產出符合標準的里氏硬度計，所以采用修改后的方法生產里氏硬度計。 然而，它與真正的里氏硬度計相去甚遠。 原廠硬度值不準的硬度計，經過校正后也能滿足準確硬度試塊的要求，所以用戶要好好選擇。

  本儀器需要注意真里氏硬度計的以下特點：

  沖擊裝置是可互換的。 一臺里氏硬度計主機可同時配備七種不同類型的沖擊裝置； 一臺主機上可以配置多臺同類型的沖擊設備。

  沖擊裝置的沖頭是可更換的。 儀器沖擊單元的沖頭是可更換的。 同類型沖擊裝置的沖頭可相互更換，不影響測量值。

  儀表不可調。 里氏硬度計出廠后不可調節(jié)。 當因球頭磨損導致測量值不準確時，應通過更換球頭來解決。

  儀器的測量誤差在全硬度范圍內均符合標準要求。 儀器的測量誤差在硬度從低到高的整個范圍內均滿足標準規(guī)定的誤差要求。

First of all, we need to understand the specifications of the workpiece we need to test and the physical properties of the workpiece such as size, thickness and surface roughness. The material of the workpiece will also have different effects on the test results, such as aluminum, copper, tool steel and other special materials, the springback modulus of different materials is different, the choice of impulse device is very important for the test results.

The purpose of purchasing the Richter hardness tester is to test the hardness values, HL, HB, HRC, HRB, HV, HS. If you meet the above conditions, you can buy a hardness tester, can improve your work efficiency. The durometer can display all six of these hardness values on a single screen.

The true Richter hardness tester conforms to national and international standards and is interchangeable. Although the relevant departments in China have formulated the Standard of The Richter hardness tester, some manufacturers have the technical strength to produce the Richter hardness tester that meets the standard, so the modified method is used to produce the Richter hardness tester. However, it is a far cry from a true Richter hardness tester. The original hardness value is not accurate hardness tester, after correction can also meet the requirements of accurate hardness test blocks, so users should choose well.

This instrument needs to pay attention to the following characteristics of true Richter hardness tester:

The impact device is interchangeable. A Richter hardness tester host machine can be equipped with seven different types of impact devices; Multiple impact devices of the same type can be configured on one host.

The punch of the impact device is replaceable. The punch of the instrument impact unit is replaceable. The punch of the same type of impact device can be replaced with each other without affecting the measured value.

Meter is not adjustable. The Richter hardness tester cannot be adjusted after leaving the factory. When the measurement value is not accurate due to the wear of the ball head, the ball head should be replaced to solve the problem.

The measurement errors of the instrument are in line with the standard requirements within the range of full hardness. The measurement error of the instrument meets the standard error requirement in the whole range of hardness from low to high.
