Product Description

Resistivity Meter, Digital

Supports the following standards: ASTM G187, ASTM G57, AASHTO T288

In addition to taking (and recording) readings manually, a Bluetooth-enabled computer (PDA, laptop etc.) can be programmed to acquire resistance readings directly from the, since the resistance meter has a built-in Bluetooth interface. 
In the latter case, the PDA or PC, which is in control of the Bluetooth link, commands the to take a reading and the resistance value is sent automatically to the PDA or PC.

When combined with appropriate electrodes (pins) and test leads, the Resistivity meter can be used to measure earth resistance with the push of a button. There is no need to adjust dials or select ranges; the Resistivity Meter automatically provides a direct resistance reading.

Depending on the application, 4-Electrode, 3-Electrode or 2-Electrode, it can be used to determine the following :

The average earth resistivity to a specific depth (with the application of an appropriate multiplier to convert resistance to resistivity, based on the electrode separation distance) – 4-Electrode Application
The resistivity of a soil sample, or of a liquid, via an electrolyte (soil/liquid) box (with the application of an appropriate multiplier to convert resistance to resistivity, depending on the box geometry) – 4-Electrode Application

The resistance-to-earth of a buried electrode, such as a ground rod, or an anode, for example – 3-Electrode Application
The resistance between two buried electrodes, such as two ground rods, or two anodes – 2-Electrode Application

It should be noted, however, that these accuracy specifications assume a low electrode (pin)/earth contact resistance during the measurement.
In this regard, it is recommended that the electrodes (pins) be firmly driven into the earth (pins cannot be loose) and, in dry soils, it is recommended that the soil around the pins be moistened in order that reliable (low resistance) contact be made to the surrounding soil.

The voltage source inside the resistivity meter that supplies the current used in the resistance measurement is a 12V(rms) crystal-controlled 82.2Hz square wave oscillator and the internal ammeter and voltmeter use very narrow band-pass filters centered at 82.2Hz. 

What this means is that resistance measurements are unaffected by any stray interference signals (having frequencies other than 82.2Hz) that may be present in the earth during the measurement.

Resistivity meter runs on a set of replaceable D-size alkaline batteries, so there is no requirement to periodically recharge the unit or to plug the unit into a power source.
Furthermore, due to its extremely low power consumption design, the can perform 10,000 single resistance readings, for example, on a fresh set of batteries.
