Fertilizer nutrient detector (YT-HB)

Features:

★ Exclusive national patent design for "Integrated Aluminum Alloy Case/Pharmacy", easy to carry, sturdy and durable, with matching testing methods and finished pharmaceuticals.

★ 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, minimizing operator errors and labor intensity.

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

The compound fertilizer nutrient content detector can detect the 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 in fertilizers, organic fertilizers (including foliar fertilizers, water-soluble fertilizers, spray fertilizers), biological fertilizers, etc., as well as the content of various heavy metals such as lead, chromium, cadmium, mercury, arsenic, nickel, aluminum, fluorine, titanium, selenium, etc.

★ 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 is accurate, ensuring the accuracy of the measurement results.

 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 nutrients: ● Organic fertilizers include available nitrogen, available phosphorus, available potassium, total nitrogen, total phosphorus, total potassium, organic matter, various humic acids, trace elements (calcium, magnesium, sulfur, iron, manganese, boron, zinc, copper, chlorine, silicon, molybdenum), and various heavy metals (lead, chromium, cadmium, mercury, arsenic, nickel, aluminum, fluorine, titanium, selenium).

 Instrument technical specifications:

9. Simultaneous, rapid, and accurate detection of nutrients such as nitrogen (N), phosphorus (P), potassium (K), and organic matter in fertilizers

10. Data printing: Built in new one click thermal printer (the first in China)

Test speed:

Test a compound fertilizer sample (N, P, K) for ≤ 50 minutes; Add 20 minutes for each additional fertilizer sample.

Test an organic fertilizer sample (N, P, K, organic matter) for ≤ 1.5 hours; Add 30 minutes for each additional sample.

Test error:

The individual error of fertilizer is ≤ 1%, and the total error of nitrogen, phosphorus, and potassium is ≤ 2%.

Product instrument features:
