The mixture of water sample, catalyst solution and strong oxidant digestion solution is heated to 120°C. The polyphosphate and other phosphorus compounds in the water sample are digested and oxidized by strong oxidants to generate phosphate under an acidic condition of high temperature and high pressure. In the presence of a catalyst, phosphate ions will form a colored compound in a strong acid solution containing molybdate. The analyzer will then measure the ABS value of the changing substance in the color, and calculate the concentration of the sample based on the calibrated data stored in the analyzer.
■ Compact modular design and small installation space of the equipment.
■ Low consumption of reagent, low secondary pollution, only 0.8mL of reagent is needed for single measurement, and the reagent can be replaced after 45 days.
■ The precision metering system is composed of imported multi-channel conjoined valve and high-precision peristaltic pump to give precision single-unit control, low failure rate, low operating cost, etc.
■ The automatic alarm mechanism has such functions as data overloaded alarm, insufficient reagent alarm, automatic diagnosis, and automatic resume operation of the system to restore power supply in the event of power/water interruption.
■ Large data storage space and user-friendly operation interface, large hard disk storage space to allow continuous storing of 100,000 historical data, a large touch screen to enhance easy operation and maintenance.
■ Can be easily operated by non-professional personnel after given with simple training.
■ Controllable water pump operation to allow free sampling time setting of water pump.
■ The equipment has a security management function to perform automatic recording and storing all control operations. The storage method is read-only mode.
■ It has a level 2 operating management authorization system where the system administrator can execute all system operations, but the general operators can only conduct daily routine maintenance and operations.
