TR-408COD ammonia nitrogen total phosphorus total nitrogen analyzer
Introduction: COD ammonia nitrogen total phosphorus total nitrogen determination principle, COD determination using digestion tube closed catalytic digestion colorimetric method, ammonia nitrogen determination using Nessler reagent colorimetric method, total phosphorus determination using closed digestion colorimetry, total nitrogen determination using alkali The persulfate digestion photometric method is approved by the US EPA. After importing cold light source, narrow-band interference technology and microcomputer, the COD, ammonia nitrogen, total phosphorus and total nitrogen values are directly displayed in units of mg/ L shows. Features: 1. It adopts imported high-brightness and long-life cold light source, which has good optical performance and the life of the light source is up to 100,000 hours. 2, 5-inch large-screen LCD screen, full Chinese display, direct data reading, simple and time-saving operation. 3, digestion colorimetric integration, no need to change the tube, the measurement is simple, fast, no safety hazards. 4. 80 standard curves and 1800 measured values (date, time, parameters, test data) can be saved. 5, memory standard working curve, the user can also calibrate the curve as needed. 6. One-button reset to factory settings, which can be quickly restored when the curve is lost due to misoperation. 7. It has a curve covering interference function to prevent misoperation of the overlay curve. 8. It has data storage function and data power-off protection function, which is convenient for querying historical measurement data and preventing data loss. 9, with a USB interface, data can be transferred to the computer for permanent storage. 10. With printing function, it can print the measured value immediately or query the history record. 11. The digestion instrument adopts intelligent PID temperature control technology and double anti-over temperature protection system, which is safe and uniform in heating and fast in speed. Through the digestion of COD, total phosphorus, total nitrogen and other projects. Technical Parameters: Measurement parameters: COD ammonia nitrogen total phosphorus total nitrogen Measuring range: 0-10000mg/L; 0-50mg/L; 0-20mg/L; 0-100mg/L Lower limit of detection: 5mg/L; 0.01mg/L; 0.02mg/L; 0.5mg/L Measurement accuracy: <5% Repeatability: <5% Optical stability: 0.001A/20 minutes (100,000 hours life) Colorimetric method: colorimetric tube colorimetric Power supply mode: AC (220V10%), 50Hz Host size: 310mm*230mm*150mm Ambient temperature: 5~40°C Ambient humidity: 85% without condensation Weight: Host <3kg, digestion 6kg
