Aoda ADS-4N Handheld digital plant nutrient meter

Aoda ADS-4N Handheld digital plant nutrient meter

ADS-4N portable plant nutrient meter, also known as plant nutrient analyzer, can instantly diagnose the relative 

chlorophyll content (unit: SPAD) or greenness, nitrogen content, leaf surface humidity, and leaf surface temperature of 

plants, so as to understand the real nitro demand of crops and the lack of soil nitro or whether too much nitrogen 

fertilizer is applied. By guiding agricultural production with this plant nutrient analyzer, the utilization rate of nitrogen 

fertilizer can be increased and the environment can be protected.

Plant nutrient meters can be widely used in agricultural and forestry-related scientific research units and universities to 

study plant physiological indicators and guide agricultural production.

Features

1. The plant nutrition meter supports fast and non-destructive detection of plant nutrition without affecting plant growth.

 2. All parameters can be measured at the same time in one operation and displayed in real time.

 3. Nitrogen, chlorophyll, leaf temperature, and leaf humidity are displayed on the same screen, can be stored at the same time, and the 

average value of the four indicators can be automatically calculated.

4. The English interface has functions such as "system settings", "view data", "energy saving settings", "clock settings", and "delete data".

5. Historical data can be viewed in sequence or in jump mode.

6. You can enter the plant name, standard nitrogen content, and utilization rate to directly calculate the standard fertilizer amount.

7. The data saved in the host will not be lost after an unexpected power outage.

8. For historical data, you can delete them one by one or delete them all with one click.

9. The plant nutrition rapid meter has a built-in USB interface, which can be connected to a computer to export the measured data, which is convenient for the 

management and analysis of plant nutrients.

10. Built-in lithium battery power supply, direct charging without battery replacement, the instrument has a backlight function.
