Advantages
- Non-destructive.
- Large areas can be covered quickly.
- Minimal affect from dissolved salts.
- Variations in electrical properties will e 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. For this reason the pad sensor is considered more accurate.
