Trace elements in plants: calcium, magnesium, sulfur, iron, manganese, boron, zinc, copper, chlorine, silicon, molybdenum, etc.

The content of various heavy metals such as lead, chromium, cadmium, mercury, arsenic, nickel, aluminum, fluorine, titanium, selenium, etc. in plants.

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: ≤ 0.1% (0.001, potassium dichromate solution)

5. Instrument stability: Drift less than 0.2% within three minutes (0.002, transparency measurement). After the instrument is turned on and preheated for 5 minutes, the display shows no digital drift within two minutes (transparency measurement), and the digital drift within five minutes does not exceed 0.3% (transparency measurement); The digital drift within 20 minutes shall not exceed 0.5% (for transparency measurement) and 0.001 (for absorbance measurement); The digital drift within thirty minutes shall not exceed 0.7% (for transparency measurement) and 0.002 (for absorbance measurement).

6. Linear error: ≤ 0.3% (detected by 0.003 copper sulfate)

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

8. Wavelength range: Red light: 680 ± 2nm; Blue light: 420 ± 2nm; Green light: 510 ± 2nm; Orange light: 590 ± 4nm

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

Test speed:

Test one plant sample (N, P, K) for ≤ 40 minutes, and simultaneously test three plant samples (N, P, K) for ≤ 1 hour.

Test error:

Test error ≤ 5%.

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, equipment, and instruments, making it easy to carry and equivalent to a small laboratory. Suitable for agricultural service departments or agricultural material distributors, fertilizer manufacturers, and farm hospitals to provide agricultural chemical services.

Easy to operate and fast, the finished medicine can be used immediately after opening the bottle, without the need for configuration.
