Let your crew work more efficiently by using a clamp-style ground resistivity meter As was explained previously, resistance is usually measured by inserting two probes into the ground and sending a current through them. This can take up quite a bit of time if you have a lot of areas to test. Instead, you can use a clamp meter to simplify things: Simply clamp the device around the ground wire to take your measurements.

I recommend:  Save time with earth ground clamp meters, available from Optimum Energy Products. Gisco also makes great clamp resistivity meters.

Get a soil resistivity meter to test for corrosivity Soil moisture and salt content affect the resistivity of the soil. If soil has a low resistivity, it is most likely corrosive. This is important to know when installing underground pipes, wires and cables. Sandy soil tends to be the least corrosive while clay soils or contaminated soils are the most corrosive.

I recommend:  Use a low-cost meter for the four-pin Wenner testing method; buy an economical meter from Advanced Geosciences. The four-pin meter from Farwest Corrosion Control Company allows you to perform a multitude of tests for different applications.

Test water purity using a low-powered water resistivity meter You don't have to use a high-powered meter for shallow applications, like testing ground water. These resistivity meters are used to test water purity and detect saline levels. You simply take samples of the water on-site and test them back at your lab.

I recommend:  Buy a great economical water resistivity meter from Heritage Geophysics. You can find a versatile meter at Siemens Water Technologies.
