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
■ Can determine the material which resistivity ≥0.002
■ Independent warning of P/N and Heavy doping, Big scale and fast select the silicon material
■ Very small which can be portable
■ Easy to operate , fast to test
■ Low price
