Advantages
- Non-destructive
- Large areas can be covered quickly
- Minimal affect from dissolved salts
- Variations in electrical properties will be largely averaged out over the field generated by the pad
The Pin Sensor
The pins are pushed into the substrate and measures DC resistance between the pins.
- Can be used in confined spaces
- Not affected by uneven surfaces
There may be slight variations in readings because the pad will give an average reading over a large area, whereas pins will give the highest reading in contact with the pins.
