Instrument Introduction The MQ-ZZY plant nutrition analyzer can instantly measure four parameters of plants: relative chlorophyll content, nitrogen content, leaf temperature, and leaf water (water thickness). Four parameters are measured simultaneously and displayed simultaneously. Provide a basis for precise fertilization and irrigation of plants, thereby avoiding waste and environmental damage caused by excessive fertilization. Beneficial for improving the utilization rate of nitrogen fertilizer and providing reliable soil and crop information for precision agriculture. Technical indicators Measurement indicators: chlorophyll, nitrogen, leaf temperature, leaf moisture (water thickness) Nitrogen range: entire process Nitrogen accuracy: 5% Chlorophyll range: 0.0-99.9 SPAD Chlorophyll accuracy: 1 SPAD Leaf temperature range: 0-60 Leaf temperature accuracy: 1 Moisture range: 0-5g/cm2 Moisture accuracy: 3% Storage capacity: 2G SD card Measurement time interval: less than 5 seconds Data storage medium: SD card storage Power supply: 4.2V rechargeable lithium battery Battery capacity: 2000mah Weight: 200g External dimensions of the host: 140 x 85 x 45mm (length x width x height) Packaging size: 300 * 250 * 150mm Packaging weight: 1.5kg Working and storage environment: 0 -50 ; 85% relative humidity
