Ceramic Needle Gauge
Ceramic pin gauges are high-precision measuring tools made of zirconium oxide ceramics. They are hard, wear-resistant, chemically resistant, insulated and anti-magnetic, with a low thermal expansion coefficient. They are suitable for micron-level precision testing. Their surface is smooth and non-magnetic to avoid scratching workpieces or interfering with precision instruments.

Ceramic Needle Gauge
A ceramic needle gauge is a high-precision measuring tool made from wear-resistant materials such as alumina or zirconia. Designed for diameter checking or clearance control, the ceramic needle gauge maintains dimensional stability, even after repeated use in harsh or abrasive environments. It is ideal for QA labs, mold inspection, and electronic manufacturing lines.
