AODA 4 IN 1 Chlorophyll SPAD rapid test plant nutrient testing machine
TYS-4N plant nutrient testing machine, which can measure the relative chlorophyll content (unit SPAD) or greenness, nitrogen content, leaf humidity, and leaf temperature of plants in real time, so as to understand the true nitro demand of plants and understand the degree of soil nitro deficiency Whether excessive nitrogen was applied. Guided by the TYS-4N plant nutrient testing machine, it can increase the nitrogen fertilizer utilization rate and protect the environment.
TYS-4N plant nutrient testing machine
1. Fast and non-destructive plant live detection without affecting plant growth.
2. All parameters can be measured simultaneously in one operation and displayed in real time.
3. The four parameters of nitrogen, chlorophyll, leaf temperature and leaf humidity are displayed on the same screen in English, which can be stored at the same time, and the average of the four indicators is automatically calculated.
4. The English interface has functions such as "System settings", "View data", "Energy saving settings", "Clock settings", "Delete data", etc.
5. View historical data, which can be viewed sequentially or jump to view.
6. You can enter the plant name, standard nitrogen content and utilization rate to directly calculate the standard fertilization amount.
7. The data that has been saved in the host after accidental power failure will not be lost.
8. Historical data can be deleted one by one, or all can be deleted with one click.
9. The instrument comes with a USB interface, which can be connected to a computer to export measurement data, which is convenient for plant nutrient management and analysis.
10. Built-in lithium battery for power supply, no need to change battery for direct charging, the instrument comes with backlight function.
