MHV-1000
Description:
MHV-1000 Micro Vickers Hardness Tester made with a unique and precision design in the field of mechanics ,optics and light source,and firstly adopted cold light source is able to produce a clearer indentation and hence a more precise measurement. By means of a 20 xlens and a 40 xlens the tester has a wider measurement field and a broader usage range. Equipped with a large LCD screen.The operation is more directly and clearly. It shows the measuring methods, the testing force, the indentation
length, hardness value, the dwell time of the testing force as well as the number of the measurement on its LCD screen .Besides, it has such functions as registering the date, and measuring results , treating the data , outputting the information with the printer,exchanging the scales among the 17 scales , saving date and linking RS232 interface, The instrument is,therefore,quite advanced and representative of the products of the same kind in the country.
The present tester,equipped with a pick up camera,can take the photos of the indentation and metallographic composition of the materials.
