The description of marble detection platform Marble measurement platform material: Based on the quality of the rock underground. It also has three characteristics---magnetic-proof, anti-corrosion, anti--deformation. 1. Marble detection platform is always the hardest granite surface. 2. The lowest temeperature coefficient, substantialy independant of temperature. 3. Resistant to moisture, corrosion, not oiled, no rust no fade. 4. The surface is wearable, non-magnetic and vains earth. 5. Almost no maitenance, can be quickly and easily clean and wipe, has good stability and accuracy.
