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). Feature about Portable Plant Chlorophyll Tester: 1. The instrument is small and convenient, one-handed operation 2. Non-destructive measurement allows rapid, non-destructive testing of plants without damaging crop growth 3.
