Surface resistivity
Surface resistivity is the resistance value per unit area. Surface
resistance formula:
ρs=Rs*
(Pereimeter/Gap)
Among them:
ρs
indicate surface r
esistivity (Ω)
Perimeter indicate effective perimeter (cm)
Gap indicate distance between main and secondary electrodes
(cm)
Rs indicate surface resistance measured
Perimeter formula:
Perimeter = π × (D2+D1)/ 2
Gap formula:
Gap = (D2 - D1)/2
Among them:
D1 indicate main electrode diameter (cm)
D2 indicate pair electrode diameter (cm)
