Function and Features
1. Large LCD color touch screen backlit Chinese display, digital circuit, programmed design.
2. It can quickly detect functions such as available nitrogen, available phosphorus, available potassium, total nitrogen, total phosphorus, total potassium, organic matter, acidity and alkalinity, and salt content in soil, fertilizers, and plants.
3. The instrument contains a "formula fertilization expert system" that can automatically calculate and provide the best fertilization plan based on the different crops and yields of the customer;
4. Recommended fertilizer application rates can be calculated for target yields of over 100 national crops, fruit trees, and economic crops. Crop varieties, crop yields, fertilizer amounts, etc. can be set according to local conditions;
5. It contains a battery and is suitable for both indoor and outdoor use. It has a time display function and can automatically record and save the time of the test sample.
6. It can store 10000 sets of test data (including the time, location, and various nutrient results of the test samples) and other related information, and the data can be accessed and viewed at any time;
7. Equipped with a micro printer, it can print out relevant information such as testing date, testing items, nutrient content, crop variety, fertilizer variety, fertilizer content, fertilizer utilization rate, and fertilizer quantity at any time, with detailed and rich content;
8. Widely applicable to various levels of agricultural technology promotion stations, fertilizer production, agricultural material management, agricultural technology services, planting bases, and other fields;
9. Electrode detection can be added: soil moisture, temperature, light, carbon dioxide, temperature and humidity, etc.
