Fertilizer rapid tester

Features:

★ Patented design of "chassis/medicine integrated aluminum alloy chassis", easy to carry, durable, supporting detection methods and finished medicines.

★ Microcomputer control, digital circuit, program design, LCD display, AC and DC dual-use, test data can be stored and queried, field flow test can be carried out, minimizing operator errors and labor intensity.

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

★ Can detect quick-acting nitrogen, quick-acting phosphorus, effective 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 and various heavy metals such as lead, chromium, cadmium, mercury, arsenic, nickel, aluminum, fluorine, titanium, selenium in fertilizers, organic fertilizers (including foliar fertilizers, water-soluble fertilizers, spray fertilizers), biological fertilizers, etc.

★Adopt high-brightness LED light source and filter treatment to ensure the stability of the light source wavelength. Silicon semiconductor is used as the signal receiving system, and the service life is up to 100,000 hours.

★The colorimetric tank adopts a single-channel design, without mechanical displacement and wear, and the optical path test positioning is accurate to ensure the accuracy of the measurement results.

Complete test items:

Fertilizer nutrients: ● Nitrogen, phosphorus, and potassium in single-element fertilizers; ● Ammonium nitrogen, nitrate nitrogen, phosphorus, potassium, and biuret in compound (mixed) fertilizers and urea;

Organic fertilizer nutrients: ● Fast-acting nitrogen, fast-acting phosphorus, fast-acting 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), etc. and various heavy metals (lead, chromium, cadmium, mercury, arsenic, nickel, aluminum, fluorine, titanium, selenium) in organic fertilizers.

Technical indicators:

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-button thermal printer

Test speed:

Testing a compound fertilizer sample (N, P, K) ≤50 minutes; each additional fertilizer sample adds 20 minutes.

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

Test error:

Fertilizer single item error ≤1%, total error of nitrogen, phosphorus and potassium ≤2%.

Instrument features:

Fertilizer nutrient rapid tester has full functions: full test items (all kinds of medicines can be purchased).

Full set of accessories: The instrument integrates medicine, instrument and instrument, which is easy to carry and equivalent to a small laboratory. It is suitable for agricultural service departments or agricultural material dealers and fertilizer manufacturers to test soil and fertilizer and identify the authenticity of fertilizers.

Easy to operate, fast speed, finished medicine can be used after opening the bottle, no configuration is required.
