Total phosphorus automatic monitoring instrument

The total phosphorus automatic monitoring instrument has the functions of automatically collecting, storing, processing, querying, displaying, and outputting all data, instrument parameters, and operation logs.

　　Total phosphorus automatic monitoring instrumentA comprehensive small-scale online automatic monitoring system has been constructed with water quality sensors as the core, combined with modern sensing technology, automatic measurement technology, automatic control technology, network transmission technology, and big data analysis and processing technology. The system is based on the mechanism of "touch screen+control board+expansion board", coupled with rich expansion interfaces, which can meet the diverse product customization needs of users. Having self inspection and self repair capabilities can greatly improve user work efficiency; Can effectively solve the problems of fluid leakage and sealing damage caused by long-term mechanical wear of injection pumps; Background absorption and turbidity correction techniques can effectively address the impact of water sample blackening (or coloration) on low concentration measurements.

Instrument Features

It has the function of automatically collecting, storing, processing, querying, displaying, and outputting all data, instrument parameters, and operation logs.

Equipped with large capacity storage, storing historical data for no less than 5 years (with a measurement cycle of 1 hour per time)

Equipped with automatic standard sample verification function

It has multiple ranges and can automatically switch ranges, and the instrument displays the final test results.

Capable of adding identification to different test data.

It has a digital communication interface that outputs commands, related data, and operation logs through the digital communication interface, and can receive remote control commands from the management platform, including remote startup, remote timing, and other functions.

Can achieve serial port output and network port output of monitoring data.

It has the function of collecting and storing waste liquid and cleaning wastewater separately.

Abnormal alarms and power outages will not result in data loss;

After abnormal reset and power failure, the instrument will automatically discharge residual reactants and restore working status.

Selecting valve components, selecting reagent sampling timing, flexible and diverse channels, with advantages such as minimum dead volume, easy maintenance, and high lifespan.

Total phosphorus automatic monitoring instrumentPrinciple:

The mixture of water sample, catalyst solution, and strong oxidant digestion solution is heated to 115 ℃. Polyphosphate and other phosphorus containing compounds in the water sample are digested and oxidized by the strong oxidant under acidic conditions of high temperature and high pressure to generate phosphate ions. In the presence of the catalyst, phosphate ions form a colored complex in a strong acid solution containing molybdate. The analyzer detects the color change and converts it into total phosphorus value output. The amount of colored complex generated is equivalent to the total phosphorus content.
