       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


Technical Feasures:

■ Resistivity：0.001～100Ω?cm

■ Accuracy：±5%±2LSB）

■ Power supply： AC 220V ± 10% ， 50HZ

■ Power consumption：Max ≤1W


Typical Customer:
