       It use Four Probe to test the resistivity and P/N type of wafers、ingots and all type of silicon materials.It can be used by Solar and Semiconductor industry.

  
Product Feasures:

■ Test the resistivity and the P/N type at the same time。

■ Power supply is 220V AC

■ Highly precise of resistivity which can be 0.001 Ω.cm
