Microcomputer Soil (Fertilizer) Nutrient Fast Tester TP-Q7

  • TP-Q7



Product Description


1. It adopts microprocessor technology, digital circuit, programming design, single chip control, touch button and LCD display.

2.Dual Usage of AC and DC(on-board)

3. It adopts optical filters as light source, silicon semiconductor as signal reception system. Its service life is as long as 100,000 hours.

4. The cartridge part adopts multifarious optical path design to avoid system error caused by different channels.

5. The working stability is six times as good as the national standard JJG179-90,and repeatability reaches the index of grating type spectrophotometer.

6. It has automatic temperature correction for the test of effective phosphorus.

7. It has built-in thermal printer to store the printed test results.

8. It has expert fertilization system software

A.It saves 39 kinds of fertilizer suggestions of crop experts,which can automatically recommend the best fertilization scheme according to crop varieties, soil content, fertilizer content and fertilizer price. It can save more than 1000 pieces of the crop experts suggestions, and can save without limit.It can print out fertilizer suggestion table.

B. The following can also be printed out: testing date, testing time, customer name, soil number, soil type, crop variety, soil content, fertilizer varieties, fertilizer price, fertilization quantity and other relevant information. The information is detailed and rich.
