Surface Resistivity, Resistance between 2 points, and Surface to Ground can all be conveniently measured in accordance with EOS/ESD Association Std S4.1. Measurements in the conductive range i.e. upto 10^5 are made at 10V and higher values at 100V. Measurements can be also be made with external probes.
Colour-coded LEDs conveniently indicate conductive, dissipative and insulative values from 10^3 to 10^12 ohms/square with under range and over range indications.
