npk soil sensor analyzer digital soil nutrient fertility npk tester

 The soil nutrient differentiation tester can detect nitrogen, phosphorus, potassium, pH value, and salinity (conductance) value. The application of this instrument has greatly eased the needs of farmers around the world to measure soil and formula fertilization, and also achieved professionalism for fertilizer manufacturers. Systematization, systemization, informationization, and dataization provide a reliable basis, and it is the first choice for soil testing and formula fertilization in the agricultural sector. The soil nutrient speed tester is widely used in agricultural inspection centers at all levels, agricultural research institutes, fertilizer production, agricultural resources management, agricultural technology services, planting bases and other fields.

 1. Five kinds of test results that can detect nitrogen, phosphorus, potassium, pH value, salinity (conductance) value can be stored on the host computer and can be printed out separately. The host computer stores the data. English LCD backlight.
2. With time display storage. The instrument has a nutrient content of 73 kinds of crops, which can output fertilizer application formulas, with charging and printing functions, and AC and DC dual-use.
3. No less than 1000 sets of test data can be stored on the host, and the data can be recalled for viewing at any time.
4. The contents of storage and printing include: test date, test time, test items, sample content, crop varieties, fertilizer varieties, fertilization quantity and other related information.
5. The fertilizer variety and crop variety can be selected on the host, the target yield can be input, and the recommended fertilization amount can be automatically calculated.
6. The fertilizer utilization rate can be arbitrarily adjusted on the host. The fertilization adjustment coefficient and crop fertilization parameters can be arbitrarily adjusted according to different regions.
7, with a review function during the test, so that the product is more convenient and reasonable (with backlight function, can adapt to night use).
8. The crop variety, crop yield, and fertilizer variety can be set according to local conditions, and the fertilizer application amount can be automatically calculated.
9. The test sample results are automatically transferred to the computer for analysis, summary, and storage, and the nutrients required for the growth and development of 73 crops can be stored in the memory; the data can be stored in the computer for data storage, remote sending, printing, or can be carried out on the host computer The soil test formula is printed out by a micro printer, AC and DC.
10. You can choose to increase the soil moisture sensor (optional).
