Aoda DPY-7PC Soil nutrient tester

Aoda DPY-7PC Soil nutrient tester

DPY-6PC Soil nutrient meter can test available nitrogen, available phosphorus, available potassium, total nitrogen, total phosphorus, total potassium, organic matter, pH, and salinity in soil, chemical fertilizers, organic fertilizers

 (including foliar fertilizers, water-soluble fertilizers, and spray fertilizers), and plants. It has two test channels and stores the nutrient requirements of 73 crops.

1. The rapid soil nutrient tester can measure available nitrogen, available phosphorus, available potassium, total nitrogen, total phosphorus, total potassium, organic matter, pH, and salinity in soil, fertilizers, organic fertilizers 

(including foliar fertilizers, water-soluble fertilizers, and spray fertilizers), and plants. Data can be stored and printed out on the main unit, which also stores the data.

2. It features time display and storage. The instrument stores the required nutrients for 73 crops and can output fertilization guidance formulas. It has charging and printing functions and is compatible with both AC and DC power.

3. The main unit can store at least 1,000 sets of test data, which can be accessed at any time.

4. The stored and printed information includes: test date, time, test items, sample content, crop variety, fertilizer type, and fertilizer application amount.

5. The main unit allows you to select the fertilizer and crop type, enter your target yield, and automatically calculate the recommended fertilizer application rate.

6. The fertilizer utilization rate can be adjusted on the main unit. Fertilization adjustment coefficients and crop fertilization parameters can be adjusted to suit different regions.

7. Bilingual switching between Chinese and English is available. The large LCD screen displays Chinese or English, providing step-by-step instructions.

8. A playback function is provided during testing, making the product more convenient and efficient (with a backlight for nighttime use).

9. Crop varieties, crop yields, and fertilizer types can be set according to local conditions, and fertilizer application rates are automatically calculated.

10. Test results are automatically transferred to a computer for analysis, summary, and storage. The computer stores the nutrient requirements for 73 crop types. Data can be stored on the computer for remote transmission and printing. 

Soil testing and formulation can also be performed on the host computer and printed out using a micro-printer, independent of the computer. Both AC and DC operating modes are supported.

11. Data can be transferred to computer via WIFI,4G.
