VC-5A1維氏硬度計(jì)（手動(dòng)轉(zhuǎn)塔）
VC-5A1 Vicker's Hardness Tester

VC-5A1維氏硬度計(jì)采用精密機(jī)械技術(shù)和光電技術(shù)的新型維氏硬度計(jì)。
　　該機(jī)內(nèi)置硬度計(jì)算器，可通過(guò)輸入壓痕對(duì)角線長(zhǎng)度，直接在LCD屏幕上顯示硬度值。試驗(yàn)力保持時(shí)間，以LCD顯示。測(cè)量系統(tǒng)采用*的測(cè)微目鏡一次測(cè)量讀數(shù)機(jī)構(gòu)，使用方便，測(cè)量精度高。
　　硬度計(jì)配可選攝影裝置，能對(duì)所測(cè)壓痕和材料金相組織進(jìn)行拍攝，適用于測(cè)量微小、薄形試件、表面滲鍍處理后的零件，是科研機(jī)構(gòu)、工廠及質(zhì)檢部門(mén)進(jìn)行研究和檢測(cè)的理想的硬度測(cè)試儀器。
　　Vicker's Low Load Hardness Tester Model VC-5A1 is a new hi-tech product integrating precision mechanical and photoelectrical technologies.
The following highlight some key features and functions of this tester:
--Micro computer control;
--Adjustment of lighting source via soft keys;
--Adjustment of pressure holding time and LED display;
--Unique measurement conversion device and unique micro eyepiece one-time measurement readout device, ensuring easy use and high accuracy;
--Camera for indention photographing and metallography
The tester is specially designed for testing minute, thin samples or parts after surface coating. For research institutes, factories labs and QC departments, this is an ideal harness testing instrument for research or measuring purposes
