Introduction The instrument can quickly detect in the soil, plant and fertilizer available nitrogen, available phosphorus, potassium, total nitrogen, total phosphorus, total potassium, organic matter content, soil salinity and soil PH value, etc, applies to all levels of agricultural test center, agricultural scientific research institutions, fertilizer production,agricultural materials management,agricultural extension service, planting base, agricultural machinery popularization, trees, flowers, environmental protection, such as vegetable base unit.
Features 1. Quick detected in soil, plants and fertilizers available nitrogen, available phosphorus, available potassium, total nitrogen, total phosphorus, total potassium, organic matter content, soil salinity and soil PH value; 2. The use of advanced cold light source, digital control and data processing technology to ensure the stability and accuracy of source data; 3. The sample chamber is square cuvette to avoid errors due to round colorimetric tube wall caused by uneven, higher measurement accuracy, while the cuvette for a variety of specifications to meet the needs of a variety of parameters detected; 4. can detect real-time data storage, storage capacity up to 50,000 group (including detection date, test items, test results); 5. The memory of the instrument calibration curve can be called directly and automatically calculate the concentration of the results, along with the 180 extension curve space, userfriendly establishment of extended range and extended test items 6. With automatic multi-linear fit function, the user can directly call the extension project curve fitting program, without having to manually calculate the curve; 7. The selection of good stability and reliability of high-end 7-inch full-color LCD touch screen, clear and comprehensive information display measurement items, absorbance, concentration and so on, full graphical man-machine interactive operation, to provide customers the most user-friendly and convenient operating experience; 8. Apparatus built high-end brand miniature thermal line printer can print test results fast, convenient data retention; 10. Support line processing test data, current data and historical data can be stored onto a computer for processing through the data line; 11.Optional soil testing, fertilizer formula software, can automatically recommend the best fertilizer program based on test data; 12. The instrument can be extended to achieve boron, manganese, iron, copper, calcium, magnesium, sulfur, chlorine, zinc, silicon and other trace elements detection.
