Introduction: The TFC-203PCA soil nutrient rapid measuring instrument quickly detects the nitrogen, phosphorus, potassium, organic matter, pH, and salt content in the soil. Application fields: Widely used in agricultural material shops, fertilizer plants, agricultural machinery companies, agricultural service departments, higher education institutions, scientific research institutes, agricultural cooperatives, large growers, etc. Features: 1. Rotating colorimetric cassette design, built-in six sample colorimetric cups, can detect 4 samples at the same time; 2. 3.1 inch LCD screen, full Chinese menu display operation process and test status, digital circuit, highly intelligent program; 3. AC/DC dual purpose, built-in rechargeable battery, can be tested in the field; 4. The host has a built-in micro printer, which can print out the test results through this machine; 5. Portable integrated design; 6. Configure computer-side crop fertilization formula software (built-in 60+ species), which can set crop varieties, crop yields, and fertilizer varieties according to local conditions, and automatically calculate the fertilization amount and print out the formula fertilization amount; 7. Single electrode socket is used, pH and conductivity sensors use the same socket, simple operation and avoid misoperation 8. Metal case, corrosion resistance, long service life 9. It can be connected to the PC upper computer program through the instrument interface, which is convenient for data export and management Technical parameter: Detection speed: test 1 soil sample (N, P, K) ≤ 30 minutes, simultaneously test 4 soil samples (N, P, K) ≤ 45 minutes (including pre-treatment); test 1 fertilizer sample (N, P) , K) ≤50 minutes, simultaneous detection of 4 fertilizer samples (N, P, K) ≤100 minutes (including pre-treatment); Test mode: rotating test The amount of cuvettes placed: the host part is no less than six Wavelength range: 420nm-700nm (red light 620±8nm, blue light 440±8nm) Linearity error: less than 3.0% Sensitivity: red light≥4.5*10^-5, blue light≥3.17*10^-3 Stability: The drift of A value (absorbance) within three minutes is less than 0.003, when the power supply voltage fluctuates by ±10%, the product transmission repeatability: A value (absorbance) is less than 0.005 Nutrient detection accuracy: ppm (parts per million) Range and resolution: 0.001-9999 Accuracy: Two decimal places PH value measurement technical parameters Test range: 1～14 Error: ±0.1 Salt content (conductivity) measurement technical parameters Test range: 0.01%～1.00% Relative error: ±5% Display: 3.1 inch LCD screen Printing: Built-in thermal printer Power supply: AC 220V/50Hz; DC 18V/5W (built-in rechargeable battery pack) Rechargeable battery: 800 mA lithium battery Battery usage: 6-8 hours of charging, 3-4 hours of use
