Veteran OwnedMeasuring Thickness and Resistivity
Eddy current meters can measure sheet resistance, thickness, resistivity, and more.
| What can be measured | Units displayed | If derived: equation & requirements |
|---|---|---|
| Sheet conductance | Mhos/square | Measured directly |
| Sheet resistance | Ohms/square | Rs = 1/Cs |
| Resistivity, bulk resistivity, volume resistivity | Ohms-cm, ohm-cm, ohm_cm, ohm cm, ohm*cm | p = Rs * T Thickness value needed |
| Thickness | Microns, MicroMeters | T = p/Rs Resistivity value needed |
Delcom meters do not directly measure the resistivity of material—instead, they measure the sheet conductance of a conductive layer. However, if the material is of uniform thickness and if that thickness is known, a Delcom meter can be used to measure, record, display, and even map the material’s resistivity.
