Portable Plant Chlorophyll Tester

Instrument use:
A chlorophyll meter instantly measures a plant's relative chlorophyll content (in SPAD) or "greenness level", giving you an idea of the plant's true nitro needs and helping you understand how nitro-deficient or excess nitrogen is in your soil. You can use this instrument to improve nitrogen fertilizer utilization and protect the environment (to prevent excessive nitrogen fertilizer application from polluting the environment, especially water sources).
