Model SR-2 Soil Resistivity Meter

ASTM G 57, ASTM G 187; AASHTO T 288

SR-2

The Model SR-2 is a very accurate resistance meter with a digital display. Push button operation and easy to change ranges make operation simple. Use in the field or lab with pins or soil boxes.
 
Use for:
4 Pin “Wenner Method” (ASTM G 57)
3 Pin “Fall of Potential”
2 Pin applications (ASTM G 187, AASHTO T288)
1 Pin “Single Rod”
Soil Boxes
Casing Shorts
Geological Studies
 
Range of 0.1 Ohm to 3.3 MegOhms
 
Features:
Digital meter readout
Push button operation
Weather/Impact resistant case
Easily move between ranges - 0.1 Ohm to over
3 MegOhms

The instrument may be used with either two (2) or four (4) pins, which are set into soil in a straight line, at equal distances. The Pins are named C1, P1, P2 and C2. Voltages are driven between C1 and C2, while resistance drop is measured between P1 and P2 (4 pin method). In the two pin method, the resistance drop is measured between C1 and C2 only. The distance between the pins is equal to the depth of the soil resistance.

The four (4) pin method has been standardized by ASTM as Standard G 57-95(a) and this method is also described in NACE Internationals, Peabody’s Control of Pipeline Corrosion, Second Edition, pg.
