Digital Soil Analysis Tester

TerraGauge is a portable digital soil diagnostic tool designed for growers who want quick, guiding soil data without waiting for lab results. TerraGauge delivers real-time readings for the key nutrients and conditions that affect your crops.

Monitor Nitrogen (N), Phosphorus (P), and Potassium (K) levels alongside pH, EC, and moisture to make better fertiliser decisions and optimize your growing environment.

TerraGauge provides instant NPK readings, which are derived mg/kg estimates based on sophisticated algorithms correlating Electrical Conductivity (EC), temperature, and moisture data. These estimates are invaluable for observing relative changes and trends in soil fertility.

The Terragauge comes fully working with the probe sensor and the digital display device with software all pre installed and ready to go out of the box.

Why Growers Choose TerraGauge

Instant Results: Get soil data in seconds, not days.
Save Money: Reduce over-fertilising and lab testing costs.
Better Decisions: Adjust nutrients based on data, not guesswork.
Portable: Take it anywhere—field, greenhouse, or nursery.
Easy to Use: Plug in the sensor and read the app. No training needed.
