Introduction: The intelligent total nitrogen analyzer KN-TN20 can measure total nitrogen quickly, accurately, and intelligently. The experimental process is simple and fast, without manual calculation of data, and total nitrogen is automatically calculated, saving labor and cost. It is suitable for all kinds of complicated The water sample is an intelligent equipment in the laboratory. Features: 1. The original chromotropic acid method is used to determine total nitrogen, and the experimental data is stable and reliable. 2. Using 16mm tube for color comparison, the concentration can be read directly without calculation. 3. Independent single optical path non-interference total nitrogen system, high precision, long life and more stable. 4. There are 99 curves in memory, of which 89 are conventional curves and 10 are fitted curves. The curves can be freely applied with the complexity of the water sample. 5. LCD liquid crystal display, user-friendly operation prompts, easier to use. 6. Built-in curves that can be revised and saved automatically, and provide saved curves for users to measure different indicators. 7. The display mode of large and small fonts can be switched freely, the display data is clearer, and the parameters are more detailed. 8. With the function of printing data, the unique printer is hidden in the instrument without taking up additional space. 9. Transmit current data and all stored historical data to the computer, and support RS232 serial port transmission. 10. Cold light source, narrow band interference, long life of light source. 11. Equipped with complete professional consumables and reagents, the measurement is more accurate, convenient and fast. 12. The instrument has a built-in data storage function, which can store 4000 data. Technical Parameters: Product model: KN-TN20 Measuring range: 0~100mg/L (segmented) The lowest detection limit: 0.5mg/L Indication error: ≤±10% Repeatability: ≤±5% Optical stability: ≤±0.005A/20min Temperature control range: 40～190℃; Batch processing: 5pcs (standard configuration)/25pcs optional; Temperature indication error: <±2℃ Uniformity of temperature field: ≤2℃ Timing accuracy: 1 second/hour Curve parameters: 99 built-in curves, 10 of which are fitted curves Store data: 4000 data can be stored Operation mode: key operation Curve parameters: The built-in standard curve can be calibrated by itself, and the calibration parameters can be saved by itself after a power failure Instrument volume: (160×190×126) mm Instrument weight: 1.6 Kg Colorimetric method: Φ16mm colorimetric tube Display screen: LCD screen Power supply: AC220V±10% / 50Hz
