TR7138 Type

The surface resistance tester is a simple tester to measure the surface resistivity, which can measure the surface impedance value of point-to-point or point-to-ground, and the test button can automatically generate a test voltage of 10V or 100V, and display the result with a colored LED signal. The instrument has high measurement accuracy, simple operation, light weight, durability and easy to carry, and is ideal for auditing and measuring surface resistance and point-to-point resistance.

Features:
• Power supply: 9 volt battery
• Test voltage: 10V/100V;
• Resistance range: 103-1012 OHM
• Indication accuracy: 10%
• Lightweight resistance tester
