Introduction: The TFC-ZNS-1 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. 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. Built-in 60 kinds of crop fertilization formulas, can set crop varieties, crop yields, fertilizer varieties according to local conditions, and automatically calculate the application rate 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 Technical parameter: 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 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 Vibration resistance: qualified 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, and when the power supply voltage is 220V fluctuates ±10%, the transmittance of the product should change ≤1% 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%
