SPAD-502DL Plus Chlorophyll Analyzer

1、 Product Introduction
SPAD-502DL PluThe chlorophyll meter can instantly measure the relative content or "greenness" of chlorophyll in plants, thereby understanding the true nitrogen demand of plants and helping you understand the degree of soil nitrogen deficiency, such as whether excessive nitrogen fertilizer is applied. You can use this instrument to improve the utilization efficiency of nitrogen fertilizer and protect the environment (preventing excessive nitrogen fertilizer from contaminating the environment, especially water sources).
