★ Exclusive national patented design of "integrated aluminum alloy chassis/medicine", easy to carry, sturdy and durable, matched with finished medicine. 

★ Microcomputer control, digital circuit, programmed design, LCD display, dual-purpose AC/DC, capable of field flow testing, minimizing operator errors and labor intensity to the greatest extent possible.

 ★ Resolution: 0.001, touch sensitive buttons, built-in new thermal printer, capable of printing test results. 

★ The fertilizer nutrient dedicated rapid detector can detect the content of available nitrogen, available phosphorus, available potassium, total nitrogen, total phosphorus, total potassium, organic matter, etc. in fertilizers and organic fertilizers. 

★ Using high brightness LED lights as the light source and silicon semiconductors as the signal receiving system, with a lifespan of up to 100000 hours. The light source is stable and has good consistency. The colorimetric groove adopts a single channel and dual optical path design, with no mechanical displacement or wear. The optical path testing positioning is precise, ensuring the accuracy of the measurement results. 

★ Adopting independent invention patent analysis method to ensure that the test results absolutely meet the national standard requirements. The fertilizer printing result shows a percentage content, with a testing error of less than 1%. 1、 Test items: Fertilizer nutrients (patented technology): 

● Nitrogen, phosphorus, and potassium in elemental fertilizers; Ammonium nitrogen, phosphorus, and potassium in compound (mixed) Hefei and urea;

 ● Available nitrogen, available phosphorus, available potassium, total nitrogen, total phosphorus, total potassium, pH, organic matter, etc. in organic fertilizers. 

2、 Technical specifications:
