Fertilizer detector

Features:

★ The “Integrated Aluminum Alloy Case/Pharmacy” is professionally designed, easy to carry, sturdy and durable, and comes with a complete set of accessories and finished pharmaceuticals.

★ Micro computer control, digital circuit, programmatic design, LCD display, dual use of AC and DC, capable of field flow testing.

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

★ It can detect the content of available nitrogen, available phosphorus, available potassium, total nitrogen, total phosphorus, total potassium, organic matter, pH, various trace elements such as calcium, magnesium, sulfur, iron, manganese, boron, zinc, copper, chlorine, silicon, molybdenum, as well as heavy metals such as lead, chromium, cadmium, mercury, arsenic, nickel, aluminum, fluorine, titanium, selenium, etc. in fertilizers and organic fertilizers (including foliar fertilizers, water-soluble fertilizers, spray fertilizers, etc.).

★ Adopting high brightness LED light source and dual dial filter processing technology, ensuring 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.

★ Adopting high-precision filter technology and independent patented analysis methods, ensuring that the detection results are superior to national standard requirements.

The fertilizer printing result is a percentage content, with a testing error of less than 0.5%.

Multi functional and complete testing items:

Fertilizer nutrients: ● Nitrogen, phosphorus, and potassium in elemental fertilizers; Ammonium nitrogen, nitrate nitrogen, phosphorus, potassium, and biuret in Hefei and urea; Organic fertilizer (foliar fertilizer) includes available nitrogen, available phosphorus, available potassium, total nitrogen, total phosphorus, total potassium, organic matter, and various humic acids. Scalable detection of trace elements such as calcium, magnesium, sulfur, iron, manganese, boron, zinc, copper, chlorine, silicon, molybdenum, as well as various heavy metals (lead, chromium, cadmium, mercury, arsenic, nickel, aluminum, fluorine, titanium, selenium).
