Leitz hardness measuring eyepiece digital vickers info. Available to purchase for immediate download. Below is an extract from the manual converted to text for a quick impression on the content. Leitz hardness measuring eyepiece digital vickers infoLEITZ hardness measuring eyepiece digital for Vickers-, Knoop- and scratch hardness testsThese are the special performance characteristics of the LEITZ hardness measuring eyepiece digital: I High rate of capture. Rapid probing of the hardness indentations with the quick adjustment of the rectangular capture marks. These permit the measurement of both diagonals directly in succession without rotation of the eyepiece head. I Most reliable probing. Because of the special design of the capture mark the probing of the hardness indentation can be carried out absolutely correctly without effect of the line width. I High measuring accuracy. me 50ox microscopic magnification with the well-known contrast rendering of the Leitz measuring optical systems and the precision linear measuring system permit the digital display in steps of 0.1 pm or 0.01 um. I Precision measured-value determination. Because of the direct connection between the capture marks and the measuring standard, the digital display can be instant. I Great saving of time. Compared with measurements with convential hardness measuring eyepieces the direct printout of the hardness values by the computing printer represents an extraordinary gain in time.
