About
A terrameter meter is an advanced geophysical instrument designed to measure the electrical resistivity of various materials, primarily used in subsurface investigations.
It typically consists of a portable control unit, electrodes, and cables to inject electrical current into the ground and measure the resulting voltage differences. This data is then used to calculate the resistivity of the subsurface materials.
Current Injection: The machine sends a controlled electrical current into the ground through the electrodes.
Voltage Measurement: It measures the voltage difference between selected electrodes.
Resistivity Calculation: The machine calculates the apparent resistivity of the ground using the measured voltage, injected current, and electrode spacing.
The resistivity meter’s portability and accuracy make it ideal for field surveys, offering a non-destructive means of probing below the Earth’s surface without the need for drilling or excavation.
Features
- Control Unit: The main body of the resistivity meter, usually equipped with a digital interface to display measurements, control current injection, and adjust operational settings
- Automatic SP Cancellation: Self potential between MN electodes impedes the measurement of resistivity and IP in geophysical survey. iSmart Terrameter is equiped with an automatic SP cancellation scheme the removes the SP voltage from interfering with your measurements.
- High Galvanic Isolation: Measuring accurate result in some geophysical methods requires a very high impedance between the transmitter and the receiver. iSmart Terrameter is designed with a complete galvanic isoation between the transmitter and receiver.
- High Noise rejection: While measuring earth's natural phenomenon like resistivity and IP, most meter are succeptible to earth's own electric and magnetic field the becomes part of the signal measured. iSmart Terrameter carries an inbuilt high order filter the removes such interference before taking measuements.
- Electrodes: Metal rods inserted into the ground to inject electrical current and measure voltage. Depending on the survey, two or four electrodes may be used
- Cables: Connect the control unit to the electrodes, transmitting current and collecting voltage signals
- Data Storage: Many modern resistivity meters come with built-in memory or interfaces to connect to external devices for data logging and analysis
- Data GPS Stamp: Measured data are stamped with GPS coordinate on the mobile app, so you never forget where you acquire a data
- Data Time Stamp: Measured data are stamped with current time on the mobile app, so you never forget when you acquire a data
