Instrument Introduction:
TPY-16ASoil nitrogen, phosphorus, and potassium detector/Soil nitrogen, phosphorus, and potassium analysisThe instrument is a soil nutrient analyzer produced by Zhejiang Topyun Agriculture Technology Co., Ltd. It is commonly used in cultivation and seed farming, mainly for detecting ammonium nitrogen, available phosphorus, available potassium, organic matter, and other nutrients in soil and fertilizers pH、 Salt and other substances. The application of this instrument has alleviated the demand for soil testing and formula fertilization among farmers in various regions, and also provided a reliable basis for fertilizer production enterprises to achieve specialization, systematization, informatization, and dataization. It is an instrument for soil testing and formula fertilization in the agricultural sector. Soil nitrogen, phosphorus, and potassium detectors are widely used in various agricultural testing centers, agricultural research institutions, fertilizer production, agricultural material management, agricultural technology services, planting bases, and other fields.

Model List:

Functional characteristics of soil nitrogen, phosphorus, and potassium detector:

1. Testing includes ammonium nitrogen, available phosphorus, available potassium, organic matter in soil and fertilizers pH、 Salt content (a solid-state sensor with non glass electrodes that can be directly buried in soil for testing and obtaining results).
2. The cassette part adopts a 16 channel solid-state module, 16 optical paths and receivers, which can be measured simultaneously or separately. The colorimetric dark box body is integrated without mechanical displacement and wear, ensuring the accuracy of the measurement results.
3. 7-inch color touch LCD display screen, easy to operate on Android system, convenient for online upgrade.
4. Built in clock chip, the screen can synchronously display Beijing time. The current year, month, day, hour, and minute.
5. GPS positioning function: It has satellite positioning functions for longitude, latitude, and altitude.
6. All functional data of the instrument are displayed on the same screen, and the instrument can display the operating steps while detecting.
7. Built in data storage, automatic storage of test data, no loss of database during power outage.
8. The host can perform functions such as single deletion, full deletion, printing data, printing environment parameters, positive and negative sorting, sorting by project name, filtering by date, etc.
9. Built in micro thermal printer (no need to replace ribbon), test results can be stored and printed on this machine, including: name of testing unit, testing date, testing time, testing items, sample content, crop variety, fertilizer variety, fertilizer quantity, measurement unit and other related information.
10. Recommended fertilizer application for calculating the target yield of 100 agricultural, fruit tree, and economic crops.
11. Data transmission can be remotely transmitted to a computer via WiFi/4G wireless. The instrument comes with a system cloud platform and a mobile app for easy management of measurement data.
12. To prevent misoperation, the host has a built-in customer management system that allows users to set their own usernames and passwords. Different users can choose their own usernames to prevent the loss of tested data.
13. Equipped with a built-in lithium battery pack, it can be used for both AC and DC, and can achieve field flow testing.
14. The instrument is versatile and can be connected to multiple sensors to measure air temperature and humidity, soil temperature, and soil moisture CO2， Parameters such as photosynthetically active radiation and light intensity (optional).

Manage cloud platform functions
1. The built-in instrument cloud management platform includes a C/S architecture, which can summarize and analyze data from all portable and online devices without losing data backup. The viewing and operation methods include web and mobile devices (Android system).
2. Display the detection time, detection items, absorbance, and concentration of each channel; And corresponding information such as crop types, fertilization types, and fertilization plans.
3. The data can be synchronized to the management cloud platform. Data within the platform can be downloaded, analyzed, and printed.
4. The platform supports the addition of multiple devices, supports cloud storage of device data, and provides sufficient capacity for long-term storage.
5. The platform provides report formats such as curves and tables for device data, and the data can be exported and imported.
6. The software can be upgraded online.
