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.
