There are different families of electrical isolation measurement devices:
Ground isolation measures. To determine ground resistance in installations (resistivity) using the Wenner or similar method.
Measurement of insulation resistance in components, equipment, tools,etc. Under the rule IEC611010-1
Measurement of specific resistance like isolation devices for aeronautics or los óhmetros pirotécnicos.
Micrómetros for the calculation of the resistance in cable industry, small electric material, etc.
