Plant Chlorophyll Tester SPAD Meter

The MQ-ZZY Plant Chlorophyll Tester SPAD Meter can instantly measure four parameters of plants, namely the relative chlorophyll content, nitrogen content, leaf temperature, and leaf moisture (water thickness). These four parameters are measured and displayed simultaneously. It provides a basis for precise fertilization and irrigation of plants, thus avoiding waste and environmental damage caused by excessive fertilization. It is beneficial for improving the utilization rate of nitrogen fertilizers and provides reliable soil and crop information for precision agriculture.
