Calibration for Accuracy
Every device ships pre-calibrated against reference standards, with in-field re-calibration when you need it.
Soil sensors drift. Every commercial soil probe on the market drifts — that's physics, not a manufacturing defect. What matters is how the manufacturer handles it.
Every KrishiLab device is factory-calibrated against NIST-traceable reference solutions for EC, pH, NPK, and moisture before it ships. The calibration coefficients are stored on-device and applied automatically to every reading.
For field re-calibration: the app includes a guided flow that uses common household references (distilled water for EC, pH-4 and pH-7 buffer sachets that we ship with the device). Re-calibration takes under 5 minutes and can be done once a season.
We also publish a public accuracy specification — no vague "highly accurate" claims. You get ± tolerance numbers for every parameter, and the test method used to derive them.
