Whole project soil and fertilizer nutrient detector

Features:

★ The design of the “Integrated Aluminum Alloy Case/Reagent Case” is easy to carry, sturdy and durable, equipped with testing methods and finished reagents.

★ Micro computer control, digital circuit, programmatic design, LCD display, dual use of AC and DC, test data can be stored and queried, and can be tested in the field, greatly reducing operator errors and labor intensity.

★ Resolution: 0.001, touch button, built-in new thermal printer, can print test results.

The soil and fertilizer nutrient analyzer for the entire project can detect various trace elements such as calcium, magnesium, sulfur, iron, manganese, boron, zinc, copper, chlorine, silicon, molybdenum, etc. in soil, fertilizers, organic fertilizers (including foliar fertilizers, water-soluble fertilizers, spray fertilizers, etc.), plants, and available nitrogen, available phosphorus, available potassium, total nitrogen, total phosphorus, total potassium, organic matter, pH value.

★ High brightness LED light source is used, with filtering processing to ensure stable wavelength of the light source. Silicon semiconductor is used as the signal receiving system, with a lifespan of up to 100000 hours. Stable light source, good reproducibility, and high accuracy.

The color comparison groove adopts a single channel design, with no mechanical displacement or wear. The optical path testing positioning ensures the accuracy of the measurement results.

★ Equipped with expert fertilization system data, it can scientifically calculate the recommended fertilization amount for the target yield of over a hundred agricultural, fruit tree, and economic crops nationwide.
