Handheld Chlorophyll Meter,Rechargeable SPAD Meter for Portable Plant Leaf Greenness Analysis,Gardening,Agricultural Research

The Chlorophyll Meter instantly measures plants' relative chlorophyll content (in SPAD units) or "greenness," indicating their actual nitrogen needs—showing soil nitrogen deficiency or over-application. It boosts nitrogen fertilizer use efficiency and protects the environment.
