Know what your soil is telling you.
Read nitrogen, phosphorus, potassium, pH, EC, salinity, moisture, and temperature in under 30 seconds—then compare zones and make better decisions while you are still in the field, bed, paddock, or block.
Best for fast trends and comparisons between lab tests. See exactly how the readings work and the important limitations.
One probe. Eight readings. A clearer picture of your soil.
TerraGauge captures the soil’s electrical and electrochemical response across its probe elements, then applies smart algorithms to turn that signal into useful nutrient, pH, salinity, moisture, and temperature insights in seconds.

TerraGauge is a complete field system: hardware for the soil, a dedicated display for the reading, and history that helps you see how your locations change over time.
The complete TerraGauge kit
Probe, dedicated touchscreen display, pre-installed standard app, USB-C charging cable, and quick-start guide—ready to use without a phone.
Build a history of every block, bed, or paddock.
Save readings by location, compare zones, and see how conditions change over time—not just what they look like today.
- Save readings to named locations
- Review history and trends over time
- Compare results across your growing areas
From soil to decision in three steps.
No phone setup, account creation, or lab queue is required to get started.
Insert the probe
Push the weatherproof stainless-steel probe into a field, bed, paddock, pot, or greenhouse zone.
Capture the reading
The included touchscreen displays the readings in seconds. Save them to a named location to compare later.
Decide where to act
Use the results to compare areas, spot changes, and decide where a closer look or lab test is worthwhile.
Built for growers who want fewer guesses.

How does TerraGauge turn a soil reading into useful information?
The probe senses the soil’s electrical and electrochemical response across its metal elements. TerraGauge then applies smart algorithms to interpret those signals across multiple sensors and produce fast, readable values for nutrient levels, pH, salinity, moisture, and temperature. The readings are designed to help you compare zones, spot changes, and decide where attention is needed. For fertiliser programmes, remediation plans, compliance reporting, or certified lab-grade confirmation, use a laboratory test.
Do I need a phone, app download, or subscription?
No. The complete kit includes a dedicated touchscreen display with the standard app pre-installed. The standard experience includes live readings, interpretation, trend charts, and unlimited readings with no subscription required. Optional Pro features can be added later.
What is included for the price shown?
The standard kit includes the TerraGauge probe, dedicated display device, pre-installed standard app, charging cable, and quick-start guide. Shipping, taxes, and any applicable duties are calculated at checkout for your delivery destination.
What if it does not suit my soil or setup?
Try TerraGauge in your own soil for 30 days. If it is not right for you, return it for a full refund subject to the applicable returns policy.

Important measurement note
TerraGauge uses electrical and electrochemical signals captured by the probe, together with algorithmic interpretation, to provide real-time soil insights. Temperature, moisture, and EC are measured directly by the probe; pH, salinity, and NPK are algorithmically calculated from the sensor response and should be used as directional trends rather than laboratory-grade figures. TerraGauge is not a substitute for certified laboratory soil testing or professional agronomic advice, and you are responsible for decisions made using this data, including those with financial consequences. To the maximum extent permitted by law, Digisect Investments Pty Ltd disclaims liability for loss arising from reliance on this data. This does not affect any consumer guarantee or right that cannot lawfully be excluded in your jurisdiction. See your applicable Terms of Use.
