Which instrument is used to measure resistivity?
GeneralClass 12AllAnswered 27 Mar 2026
Answer
Several instruments measure resistivity:
- Four-point probe resistivity meter: Industry standard for semiconductors and thin films
- Earth/Ground resistance tester: Measures soil resistivity
- Megohmmeter (Megger): Measures high-resistance materials
- Digital multimeter with four-wire resistance: For precise measurements
- LCR meter: Measures resistance, inductance, and capacitance
- Conductivity meter: Indirectly measures resistivity of solutions
The choice depends on the material type, expected resistivity range, and reuired accuracy.
