The Hammond two-probe Resistivity Meter measures electrical resistance giving an indication as to the possible rate of embedded steel corrosion.
- Indicates possible corrosion rates of rebars
- Easy and quick to use
- Handheld & battery powered
- Fast (less than 2.5 minutes to test)
- 3 digital LCD display
- Complete with 6.5mm drill bit, drill template for hole spacing, syringe, couplant gel and lead
How to use: Drill 2 x 6.5mm deep holes using the drill bit and template provided, inject couplant into the holes and take a reading using the probe.
How to read results:
(p = resistivity)
p ≥ 20kΩcm is low
10kΩcm > p < 20kΩcm is low/moderate
5kΩcm > p < 10kΩcm is high
p ≤ 5kΩcm is very high
If you have any further questions about how to read the results, email or phone us and we can help you out.
