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

11. Testing speed: Test a fertilizer sample (N, P, K) for ≤ 50 minutes (including pre-treatment time, no need for users to provide any attachments)

12. Simultaneously test 5 fertilizer samples for ≤ 2 hours (including pre-treatment time)

13. Data printing: Built in new one click thermal printer

Test speed:

Can simultaneously detect 8 samples;

Test a compound fertilizer sample (N, P, K) for ≤ 50 minutes; For every additional fertilizer sample, the time increases by 20 minutes.

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

Product instrument features:

Fully functional: The testing items are comprehensive both domestically and internationally (all types of drugs can be purchased).

Fully equipped, this instrument integrates medicine, apparatus, and instruments, making it easy to carry and 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 level of the grating spectrophotometer index.
