soil hardness tester,
soil testing laboratory equipment
STR113 Soil nutrient speedometer
1. Detection functions include ammonium nitrogen, available phosphorus, available potassium, organic matter, PH and salt in soil and fertilizer.
(salt and PH tests are optional)
2. 8/16 through the optical system, multiple samples were detected rapidly at the same time
3, 7-inch LCD Chinese display, user-friendly operation interface, accurate reading, intuitive, built-in GPS module, real-time location of latitude and longitude.
4, high degree of intelligence: automatic diagnosis system failure, with voice operation tips
5. Built-in micro printer can print test results in real time. The storage and printing contents should include: name of test unit, test date, test time, test item, sample content, crop variety, fertilizer variety, fertilization quantity, measurement unit, latitude and longitude, altitude, temperature and humidity, radiation data and other relevant information.
6, the use of wifi interface design, convenient data storage and movement, can achieve data query, browsing, analysis, statistics and release, data transmission can be wifi or GPRS wireless remote transmission of data to the computer.
7. The whole machine adopts new instrument structure design: small size, easy to carry, no mechanical moving parts, anti-interference, anti-vibration, high detection accuracy, long instrument life, equipped with built-in high-power lithium battery pack, both ac and dc, can realize field flow test.
8. Can store ≥ 200,000 pieces of testing information, automatic data saving function, no loss of stored data after power failure, with perfect query and statistics function
9, 105 kinds of national agriculture, fruit trees, cash crops target yield calculation recommended amount of fertilizer.
10. The instrument can be extended to access a variety of sensor data, such as soil salinity and soil moisture.
11. You can delete the data on the host, delete it all, print the data, print the environment parameters, sort by project name, sort by date and other functions
12. The device can set password, and different users can choose their own user names to prevent the loss of measured data
