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.
