Granite Measuring Tools & Componenets are made of special granite rock. They are more and more extensively used in scientific researching activities, because of its high precision, high hardness, high stability and corrosion resisitant.

We can also make the granite measuring tools according to GGG-P-4630 DIN876; BS-817; JIS-B510; ISO-DP8512 standards, and accept buyer's drawings.
