adoption of structural ceramic materials in the precision gauge has the unmatchable advantages than the traditional alloys:
For its high resistance to wear and corrosion, under the hostile environments, the service life is 3 to 5 times of the alloys gauges；
◆For its low thermal expansion (W/m.K 2.5), the high temperature will not easily make this material expanded, so that the measurement accuracy can be guaranteed；
◆For its extra-high hardness, it can reach high precision while avoid deforming;
◆The lighter weight of zirconia material makes it convenient for transportation, storage and usage；
◆The daily maintenance will be convenient and economical for the smooth surface and the resistance to wear and wetness；
The precision gauges in accordance with the international alloy standard or of non-standard can be available (mainly blanks).
