• The “aluminum alloy case with built-in reagents” design is easy to carry, durable, easy to operate, and fast. It comes with ready-to-use reagents that require no preparation, making it equivalent to a small laboratory. It is suitable for agricultural service departments, agricultural suppliers, and fertilizer manufacturers for soil testing, fertilizer application, and fertilizer authenticity verification.

• Tests for 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.

• Microcomputer control, digital circuitry, programmable design, LCD display, AC/DC dual-use, suitable for field testing, significantly reducing operator errors and labor intensity.

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

• Utilizes high-precision filter plate technology and proprietary analytical methods (Patent No.: ZL 2018 2 1777724.7) to ensure testing results exceed national standard requirements.

• Equipped with expert fertilization system data, it can scientifically calculate and recommend fertilization amounts for over 100 types of national agricultural, fruit tree, and economic crops based on target yields.

• The colorimetric cell section adopts a single-channel design, eliminating mechanical displacement and wear, ensuring accurate optical path testing and positioning, and guaranteeing measurement accuracy.

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

• Comprehensive functionality: test items are complete both domestically and internationally (various reagents are available for purchase).
