LONGF-L Total Phosphorus Water Quality Online Analyzer
Introduction: After the water sample and the masking agent are mixed, the total phosphorus in the form of free ammonia or ammonium ions will react with the salicylic acid color reagent to form a colored complex in the presence of an alkaline environment and a sensitizer. , The analyzer detects the change of this color, and converts this change into the total phosphorus value and outputs it. The amount of colored complexes produced is equivalent to the amount of total phosphorus. Application: water quality monitoring; water treatment discharge; environmentally friendly biopharmaceuticals; petrochemical energy. Features: 1. Unique design: Compared with similar products, it has lower failure rate, lower maintenance, lower reagent consumption and higher cost performance; 2. Select valve components: select reagent sampling sequence, flexible and diverse channels, easy to maintain and long life. 3. Metering component: the accurate metering of reagents is realized through the visible photoelectric system, and the precise quantification of trace reagents is realized at the same time; 4. Sampling components: negative pressure suction by the peristaltic pump, there is an air buffer between the reagent and the pump tube, which avoids the corrosion of the pump tube; 5. Sealed digestion components: high temperature and high pressure digestion system speeds up the reaction process and overcomes the corrosion of the equipment caused by the volatilization of gas in the open system; 6. Reagent tube: Imported new-type PTFE transparent hose with a diameter greater than 1.5mm, which reduces the chance of water sample particle clogging. Technical parameter: Method basis: National Standard GB11893-89 "Water Quality-Determination of Total Phosphorus-Ammonium Molybdate Spectrophotometric Method" Measuring range: 0～500mg/L total phosphorus (classification ～2mg/L; 0.1～10mg/L; 0.5～50mg/L; 1～100mg/L; 5～500mg/L) Indication error: ≤0.5mg/L: ±0.05mg/L; 0.5mg/L: ±10% No more than ±5% No more than ±10% within 24h The minimum measurement period is 30 minutes, and the color development time can be arbitrarily modified from 5 to 120 minutes Sampling period: time interval (10～9999min arbitrarily adjustable) and whole point measurement mode Calibration period: 1～99 days, adjustable at any interval Output: 4～20mA (2 channels) RS232, RS485 Environmental requirements: Indoors with adjustable temperature, recommended temperature +5～28℃; humidity ≤90% (no condensation) Power source: AC220 ±10%V, 50 ±10%Hz, 5A Dimensions: height 1500 × width 550 × depth 450 (mm) Others: Abnormal alarm and power failure will not lose data; touch screen display and command input; abnormal reset and power failure, the instrument will automatically discharge the residual reactants in the instrument and automatically restore the working state.
