首先，我們需要了解我們需要檢測(cè)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(zhì)也會(huì)對(duì)測(cè)試結(jié)果產(chǎn)生不同的影響，如鋁、銅、工具鋼等特殊材質(zhì)，不同材質(zhì)的回彈模量不同，沖量裝置的選擇極為重要 為測(cè)試結(jié)果。

  購買里氏硬度計(jì)的目的是需要測(cè)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(tái)硬度計(jì)，可以提高您的工作效率。 硬度計(jì)可以在一個(gè)屏幕上同時(shí)顯示以上6個(gè)單位的硬度值。

  真正的里氏硬度計(jì)符合國家和國際標(biāo)準(zhǔn)并且可以互換。 雖然國內(nèi)有關(guān)部門制定了里氏硬度計(jì)標(biāo)準(zhǔn)，但一些廠家有技術(shù)實(shí)力生產(chǎn)出符合標(biāo)準(zhǔn)的里氏硬度計(jì)，所以采用修改后的方法生產(chǎn)里氏硬度計(jì)。 然而，它與真正的里氏硬度計(jì)相去甚遠(yuǎn)。 原廠硬度值不準(zhǔn)的硬度計(jì)，經(jīng)過校正后也能滿足準(zhǔn)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(jì)的以下特點(diǎn)：

  沖擊裝置是可互換的。 一臺(tái)里氏硬度計(jì)主機(jī)可同時(shí)配備七種不同類型的沖擊裝置； 一臺(tái)主機(jī)上可以配置多臺(tái)同類型的沖擊設(shè)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(cè)量值。

  儀表不可調(diào)。 里氏硬度計(jì)出廠后不可調(diào)節(jié)。 當(dāng)因球頭磨損導(dǎo)致測(cè)量值不準(zhǔn)確時(shí)，應(yīng)通過更換球頭來解決。

  儀器的測(cè)量誤差在全硬度范圍內(nèi)均符合標(biāo)準(zhǔn)要求。 儀器的測(cè)量誤差在硬度從低到高的整個(gè)范圍內(nèi)均滿足標(biāo)準(zhǔn)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.
