ZD-SF1 High-Standard Basic Soil Nutrient Rapid Tester

I. Product Introduction:

The Soil Nutrient Rapid Tester, also known as the Soil Testing and Formula Fertilization Instrument, integrates reagents, instruments, and equipment into one system. It is equipped with all necessary tools for specified chemical tests and can operate independently in villages or towns for on-site measurements, as well as perform rapid testing in laboratories. It directly prints test results and provides scientific guidance for formula fertilization. The instrument utilizes a single-chip microcomputer and large-scale integrated circuits, offering high precision, fast testing speed, intuitive readings, and user-friendly operation.

II. Performance Features:
1. Microcomputer-controlled with digital circuitry and programmed design, LCD display, AC/DC dual power supply, suitable for mobile field testing, reducing operator errors and labor intensity.
2. Resolution: 0.001, touch-sensitive keys, built-in high-end thermal printer for printing test results.
3. The soil nutrient rapid tester uses high-brightness LED lights as the light source and silicon semiconductors as the signal reception system, with a lifespan of up to 100,000 hours. The light source is stable and consistent.
4. The colorimetric槽 section adopts a single-channel, dual-light path design, with no mechanical displacement or wear, ensuring precise optical path positioning and accurate test results.

5. Comprehensive配套: The soil nutrient rapid tester integrates reagents, equipment, and instruments into one portable unit, equivalent to a small laboratory. Suitable for agricultural service departments, agricultural material distributors, and fertilizer manufacturers for soil testing, fertilization guidance, and fertilizer authenticity verification.
6. Simple operation and fast speed; ready-to-use reagents require no preparation.
7. Reliable performance: Operational stability is six times better than the national standard JJG179-90, with repeatability reaching the level of grating spectrophotometers.

III. Test Items:
1. Soil nutrients: ● Ammonium nitrogen, available phosphorus, available potassium, moisture, organic matter, acidity and alkalinity (pH test paper method), etc.;

2. The soil nutrient rapid tester can simultaneously test 8 samples;

3. Testing one soil sample (N, P, K) ≤30 minutes; testing three soil samples (N, P, K) simultaneously ≤40 minutes.
