Agronomists walking trial plots to judge nitrogen status, or guiding variable-rate fertilizer, need a reading per leaf in seconds without cutting anything. This SPAD-type meter clips a 2 × 3 mm area and returns a relative chlorophyll index of 0–99.9 in under 2 s, repeatable to ±1.0 unit. Up to 4000 readings are stored with GPS position.
