Multiple functions and 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; ● Quick-acting nitrogen, quick-acting phosphorus, quick-acting potassium, total nitrogen, total phosphorus, total potassium, organic matter, various humic acids, etc. in organic fertilizers (foliar fertilizers). It can be expanded to detect trace elements such as calcium, magnesium, sulfur, iron, manganese, boron, zinc, copper, chlorine, silicon, molybdenum, and various heavy metals (lead, chromium, cadmium, mercury, arsenic, nickel, aluminum, fluorine, titanium, and selenium).

11. Test speed: ≤50 minutes to test one fertilizer sample (N, P, K) (including pre-processing time, no accessories required by the user)

12. ≤2 hours to test 5 fertilizer samples at the same time (including pre-processing time)

13. Data printing: built-in new one-button thermal printer

Test speed:

8 samples can be tested simultaneously;

Test one compound fertilizer sample (N, P, K) ≤50 minutes; 20 minutes more time for each additional fertilizer sample.

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

Test error:

The single error of fertilizer is ≤0.5%, and the total error of nitrogen, phosphorus and potassium is ≤1%.

Instrument features:

Full functions: Comprehensive test items at home and abroad (all kinds of agents can be purchased).

Completely equipped, the instrument integrates medicine, equipment and instrumentation, is easy to carry, and is equivalent to a small laboratory. Users only need to provide distilled water to complete all operations within the required time.

Reliable performance: The working stability is more than 8 times better than the national standard JJG179-90 index, and the repeatability reaches the index level of the grating spectrophotometer.
