• This model is an upgraded version of the full-project soil fertilizer nutrient analyzer, featuring a powder-coated steel plate housing for durability and reliability, along with a complete set of accessories and ready-to-use reagents.

• Microcomputer-controlled with digital circuitry and programmable design, LCD display, and compatible with both AC and DC power sources, enabling field testing.

• It measures available nitrogen, available phosphorus, available potassium, total nitrogen, total phosphorus, total potassium, organic matter, pH, calcium, magnesium, sulfur, iron, manganese, boron, zinc, copper, chlorine, silicon, molybdenum, and other trace elements, as well as lead, chromium, cadmium, mercury, arsenic, nickel, aluminum, fluorine, titanium, selenium, and other heavy metals.

• Utilizes high-brightness LED light sources and dual-wheel filter-based processing technology to ensure stable light source wavelengths, with silicon semiconductors as the signal reception system, offering a lifespan of up to 100,000 hours, stable light sources, excellent reproducibility, and high accuracy.

• The colorimetric cell section adopts a single-channel design with no mechanical displacement or wear, ensuring accurate optical path testing and positioning to guarantee measurement accuracy.

• It is compatible with expert fertilization system data, enabling scientific calculation and recommendation of fertilization quantities for over a hundred types of agricultural, fruit tree, and cash crops based on target yields.

• Resolution of 0.001, touch-sensitive buttons, and an built-in thermal printer for printing test results.

• Utilizes proprietary patented analytical methods to ensure testing results meet national standards.
