Wenner 4 Probe test is one of the most common soil resistivity testing methods. It is also part 3 in a series of short posts on Soil Resistivity Testing Methods. Part 1 & Part 3. Together with, the common mistakes encountered. And also, practical advice on how to avoid the Soil Resistivity Testing 10 Common Mistakes.
Soil Resistivity Testing Methods – The Wenner 4 Probe
So soil resistivity testing can be carried out using different methods. Therefore, below describes the Wenner 4 Probe Test Method. Also, its one of the three most popular soil resistivity methods employed, to perform a soil resistivity test:
Wenner 4 Probe Soil Resistivity Testing Method
Wenner array is probably the most labour-intensive of all the ways when performing the longer traverses. Hence, this method can call on up to four people to accomplish the task in a sensible time frame.
On the other hand, it is the optimal Soil Resistivity Testing Method (to date) of choice for Earthing Designs, due to its ratio of received voltage per unit of transmitted current.
Therefore, this means the Wenner Method is considered one of the more ‘reliable’ methods for testing soils to deeper depths. Click here for full article...
