 Products Description 

Application Methods of Semiconductor Power Tester Resistivity (Model ST-2722-SZ)
The ST-2722-SZ model can measure the resistivity of virtually any semiconductor powder material without specific material limitations. The only requirement is that the sample’s resistivity falls within the instrument’s measurable range.

Measurement Range and Resolution
Resistivity Measurement Range:

15.0 × 10⁻⁶ Ω·cm to 200.0 × 10³ Ω·cm

Resolution:

1.5 × 10⁻⁶ Ω·cm to 0.1 × 10³ Ω·cm (for the range 1.0 × 10⁻⁶ to 200.0 × 10¹ Ω·cm)

0.1 × 10⁻⁶ Ω·cm to 0.1 × 10¹ Ω·cm

Powder Sample Requirements
Applicable Powders: All types of powder materials can be measured.

Recommended Particle Size: Below 40 mesh; maximum particle size should not exceed 10 mesh. Very fine powders may not significantly impact measurement accuracy.

Instrument Components and Parameters
Digital Voltmeter:

Measurement Range: 200 mV to 2.0 V (automatic range selection)

Display: 4 significant digits, maximum display 200.0 units with automatic unit selection

Digital Controlled Constant Current Source:

Output Current: Direct current adjustable from 0.1 µA to 1000 mA

Stepwise automatic adjustment of current
