Characteristics: 1. The three parameters (chlorophyll, nitrogen, leaf temperature) can be stored and can be saved, which can be used to plot the distribution patterns of plant nutrients, and provide the basis for accurate fertilization of plants. 2. Rapid and non-invasive plant testing does not damage crops and does not affect plant growth. 3. Rapid determination of multiple parameters: simultaneous determination of chlorophyll, nitrogen and leaf temperature in a single operation. 4. Acquisition of location information of test points: received by serial port interrupt mode through the GPS module built into the instrument, through NAME-83 protocol, the received data is decoded into longitude, latitude, speed, time (clock and calendar). The time can be set manually. (multifunctional model with this function) 5. Historical data view, three parameters at the same time. 6. Color screen measurement results show that visual and clear, with backlight function. 7. The measurement data is convenient to save and the historical data is displayed intuitively. 8. Built-in rechargeable battery, easy to carry and use. Technical parameters: Determination index: nitrogen, chlorophyll, leaf temperature, Nitrogen range: total Nitrogen accuracy: ±5% Chlorophyll range: 0.0-99.9 Spad chlorophyll precision: ±2Spad Leaf temperature range: 0-90 ℃ Leaf temperature accuracy: ±1 ℃ Storage capacity: 999 group data
