Alumina Ceramic Needle Gauge

 
Alumina ceramic needle gauge is based on the current testing equipment used in the tungsten steel needle regulation of poor corrosion resistance, short life defects, as well as the white steel needle gauge connection is not reliable, easy to rust and fragmentation of the status quo and developed high-tech products.

Alumina ceramic needle gauge characteristics are: With the media contact surface and working face are alumina ceramic needle gauge, no special protection is required. With the existing ceramic needle gauge ratio, with anti-embroidery, can washed, corrosion resistance, high strength characteristics, at the same time alumina ceramic needle gauge service life is 10 times times higher than tungsten steel white steel needle gauge, but also can improve the life of sealing filler, with a very high wear resistance, corrosion resistance, impact resistance characteristics.
