Microcomputer soil nutrient rapid measuring instrument Automatic soil nutrient tester
Products Description
Feature
1. Adopt microprocessor technology, digital circuit, programmed design, single-chip control, touch button, and liquid crystal display.
2, cross, straight (vehicle) dual purpose.
3. The filter is used as the light source, and the silicon semiconductor is used as the signal receiving system, with a life span of up to 100,000 hours.
4. The cassette part adopts the design of double multi-optical path mechanism, which avoids the systematic error caused by different channels.
5. The working stability is 6 times better than the national standard JJG179-90 index, and the repeatability reaches the index of grating spectrophotometer.
6. The test of effective phosphorus has the function of automatic temperature correction.
7. Built-in thermal printer to store and print test results.
8. Expert fertilization system software
A. It stores 39 kinds of crop expert fertilization suggestions. It can automatically recommend fertilization plans according to crop varieties, soil content, chemical fertilizer content, and chemical fertilizer prices. It can save more than 1,000 items, and can save and print fertilization suggestion sheets without limitation.
