Fertilizer Content Detector

Characteristic:

★ Upgraded version, with a spray painted steel plate shell design, sturdy and durable, equipped with a complete set of accessories and finished chemicals.

★ Microcomputer control, digital circuit, programmed design, LCD display, dual-purpose AC/DC, capable of field flow testing.

★ Resolution: 0.001, touch sensitive buttons, built-in next-generation thermal printer, capable of printing test results.

★ It can detect the content of available nitrogen, available phosphorus, available potassium, total nitrogen, total phosphorus, total potassium, organic matter, acidity and alkalinity, 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 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. The light source is stable, with good reproducibility and high accuracy.

The colorimetric groove adopts a single channel design, with no mechanical displacement or wear. The optical path testing positioning is precise, ensuring the accuracy of the measurement results.

★ Adopt independent patent analysis method (patent number: ZL 2018 2 1777724.7) to ensure that the test results meet the national standard requirements.

★ Equipped with a thermal printer, the fertilizer printing results are in percentage content, with a testing error of less than 0.5%.

Instrument technical specifications:

1. Power supply: AC 220 ± 22V DC 12V+5V (can be powered by a car power supply or choose the instrument's built-in lithium battery)

2. Power: ≤ 5W

3. Range and Resolution: 0.001-9999

4. Repeatability error: ≤ 0.02% (0.0002, potassium dichromate solution)

5. Instrument stability: The digital drift within two hours is less than 0.2% (0.002, measured for transparency). After the instrument is turned on and preheated for 5 minutes, the display shows no digital drift within one hour (transparency measurement), and the digital drift within two hours does not exceed 0.2% (0.002, transparency measurement).

6. Linear error: ≤ 0.1% (0.001, copper sulfate detection)

7. Sensitivity: Red light ≥ 4.5 × 10-5 Blue light ≥ 3.17 × 10-3 Green light ≥ 2.35 × 10-3 Orange light ≥ 2.13 × 10-3

9. PH value (pH): (1) Test range: 1-14 (2) Accuracy: 0.01 (3) Error: ± 0.1

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

14. Reserve a 232 data interface that can be connected to a computer for data transmission.

Test speed:

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

Instrument features:

Fully functional: The testing items are the most comprehensive both domestically and internationally (all kinds 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. Suitable for agricultural service departments or agricultural material distributors to identify the authenticity of fertilizers, fertilizer manufacturers to control fertilizer production, and agricultural material quality inspection departments to crack down on counterfeit agricultural materials and regulate the agricultural material market.

Reliable performance: The working stability is more than 10 times better than the national standard JJG179-90 index, and the repeatability reaches the level of the grating spectrophotometer index.
