Plant Nutrition Tester

Technical indicators:

1. Power supply: AC 220±22V DC 12V+5V (car power supply can be used or built-in lithium battery can be selected)

2. Power: ≤5W

3. Range and resolution: 0.001-9999

4. Repeatability error: ≤0.1% (0.001, potassium dichromate solution)

5. Instrument stability: drift within three minutes is less than 0.2% (0.002, transmittance measurement). After the instrument is turned on and preheated for 5 minutes, the displayed digital display will have no drift within two minutes (transmittance measurement), and the digital drift will not exceed 0.3% within five minutes (transmittance measurement); the digital drift will not exceed 0.5% (transmittance measurement) or 0.001 (absorbance measurement) within 20 minutes; the digital drift will not exceed 0.7% (transmittance measurement) or 0.002 (absorbance measurement) within 30 minutes.

6. Linear error: ≤0.3% (0.003 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

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-button thermal printer

Test speed:

Test one plant sample (N, P, K) ≤40 minutes, and test three plant samples (N, P, K) at the same time ≤1 hour.

Test error:

Test error ≤5%.

Features:

Full function: comprehensive test items at home and abroad (all kinds of drugs can be purchased).

Complete supporting facilities: The instrument integrates drugs, instruments and instruments, which is easy to carry and equivalent to a small laboratory. Suitable for agricultural service departments or agricultural material dealers, fertilizer manufacturers, and farmers’ hospitals to provide agricultural chemical services.

Easy to operate, fast, the finished medicine is ready to use after opening the bottle, no configuration is required.
