Semiconductor Powder Resistivity Tester
Application Methods
The Semiconductor Power Tester Resistivity in type ST-2722-SZ can measure the resistivity of any semiconductor powder material. It has no requirement for materials. It only requires the sample`s test value to be within the measuring range of the instrument.
Measuring range.resolution
Resistivity:15.0×10-6 ~ 200.0×103 Ω-cm resolution:1.5×10-6 ~ 0.1×103 Ω-cm (1.0×10-6 ~ 200.0×101 Ω-cm resolution:0.1×10-6 ~ 0.1×101 Ω-cm)
