The Trescon P511+OA110 ammonia nitrogen total phosphorus online monitoring instrument uses the ammonia sensing electrode sensing principle for online ammonia nitrogen determination, while the molybdenum blue colorimetric method is used to test the concentration of orthophosphate. The ammonia nitrogen analysis module and total phosphorus analysis module of the ammonia nitrogen total phosphorus online monitoring instrument are independent of each other and do not interfere with each other, with the characteristics of more accurate and stable testing and stronger anti-interference.

1、 Host introduction: Trescon online multi parameter nitrogen and phosphorus analyzer

For those who require accurate testing andReal time adjustment of water treatment processFor their application, Trescon is their wise choice. Compared to on-site direct input sensors, Trescon has the characteristics of more accurate and stable testing, and stronger anti-interference. Trescon adopts a modular design, allowing up to 3 modules to be freely combined. The multi parameter monitoring system has unparalleled cost advantages.

①System control module
This module is the central controller of Trescon, which consists of a high-performance microprocessor, a large-sized chart display screen, an operation control panel, and various input/output interfaces. The signals transmitted from the analysis module are processed by the main controller and displayed on the screen in a simple and understandable format, including test results, calibration records, historical data, system recorders, etc. The controller designed with intelligence can automatically recognize newly installed analysis modules. If replacing an old analysis module, the parameters related to the old module can be automatically uploaded without the need for manual re-entry, which is very convenient.

②Analysis module
The functions of each analysis module are independent of each other and do not interfere with each other. A maximum of 3 analysis modules can be combined arbitrarily, and 3 different parameters of the same test point can be tested, as well as the same or different parameters of 3 different test points. The system can automatically recognize newly installed analysis modules.

There are six different analysis modules:
Ammonia nitrogenAnalysis module OA110
Nitrate nitrogenbranchAnalysis module ON210
Nitrogen nitrate/SACAnalysis module OS210
Nitrous acid nitrogenAnalysis module ON510
phosphateAnalysis module OP210
Total phosphorusAnalysis module OP510

The testing process is as follows: enter some necessary parameters on the keyboard, and the host will download the relevant information to the analysis module. The microprocessor on the module will start the test and automatically run the logic according to the set program. The test results and possible fault information will be transmitted to the host for further processing. If you want to install a second or even a third module in the future, it's very simple. Even untrained personnel can easily complete it because the module is plug and play. Just align it with the slot and install it. Then connect the colored marked hose and restart the analysis system.

③System installation
The standard configuration is a wall mounted stainless steel installation bracket, with power components pre installed on the bracket.

④tryAgent tray
The reaction reagents, standard solutions, and calibration solutions required for system operation are all packed in specific containers and placed together on the reagent tray. The containers are labeled with different colors to facilitate quick filling of reagents and avoid incorrect filling.

Testing principle
The total phosphorus module is divided into two parts, the first part isHigh temperature chemical digestion moduleUsed to heat and digest the sample, the second part isAnalysis moduleUsed to test phosphate concentration.
During the digestion process, all valence states of phosphorus compounds are converted into orthophosphate that can be analyzed by photometry. The reaction is based on the oxidation of other valence states of phosphorus to orthophosphate under acidic conditions, namely PO43-. High temperature and high pressure conditions can greatly shorten the digestion time.
AdoptingMolybdenum blue colorimetric methodTest the concentration of orthophosphate: Add molybdate to the sample, react chemically to make the sample blue, sense the color change with a photometer, and then convert it to concentration. The entire process is carried out in an orderly manner under the control of the controller, thus ensuring high operational safety.

System Overview
The new generation Trescon Total Phosphorus (TP) analysis module can continuously monitor the total phosphorus content of various water bodies online.
The system consists of two modules, including a high-temperature chemical digestion module and a photometer analysis module, which can achieve fast and complete testing. Like other modules, it has AutoClean and AutoCal functions, ensuring maintenance savings and continuous reliable operation. As long as Trescon has two empty slots, the total phosphorus analysis module can be installed.

Testing principle
The online ammonia nitrogen testing adopts the principle of ammonia sensing electrode sensing. Add NaOH solution to the sample, mix thoroughly, and adjust the pH value of the sample to>12. At this point, all ammonium ions are converted into gaseous NH3. In addition, add chelating agents such as EDTA to adjust the sample and prevent the formation of calcium salt precipitation.
The free ammonia gas passes through a semi permeable membrane (made of Teflon) and enters the interior of the ammonia sensing electrode to participate in chemical reactions, changing the pH value of the electrolyte inside the electrode. The change in pH value is linearly related to the concentration of NH3, which is sensed by the electrode and converted into the concentration of NH4-N by the host.
