JX2008-LD resistivity tester is a portable and multi-functional 4 probes resistivity testing instrument, which is based on the principle of the four-point probe measurement. It can be used to measure the radial and axial resistivity of the sheet or block semiconductor materials and is widely applied for filtration in semiconductor and solar industries. 

• Preset the sample thickness with the self-correcting function
• Measure the resistivity and show the value directly
• Test the P/N type of semiconductor accurately
• Set up the alarm threshold of the P/N type

• Power Adaptor: Input: 100 - 240V AC, 50/60Hz, 0.8
• Output: +15V, 2.0 A
• Size: 155×120×50mm
• Testing Range: 0.001-100 ohm-cm
