Product Presentation

    KLD-C-NH3-N & PO4 & TN is an automatic on-line analyzer independently developed by KLD. Using imported CPU, highly precise signal processor and simple but steady loop flow system to effectively reduce signal fluctuation and to ensure the accuracy and stability of data. Complete separation between electronics and hydraulics allows long-term & stable running. It is suitable for several types of water matrix like river water, surface water and industrial effluent.


Features

1.      Robust & Reliable

Designed for on-line industrial and environmental applications. Complete separation between electronics and hydraulics allows long-term stable operations.

2.      Precise Reagent Dosage

CPU controlled photoelectric dosing system for accurate reagent dosage. Simple & steady structure ensures long-term service life.

3.      Easy Installation

Delivered after a long & successful series of factory tests, it is ready for installation and setup. To start monitoring just need to connect reagent tubes, sample tube, water tube, waste tube and power supply, then set up the parameters.

4.      Automatic Calibration

The analyzer performs calibration according to the calibration interval and type set up by users. If the result exceeds selected limits, the original calibration parameters will not be updated and an alarm signal will be outputted.

5.      Automatic Monitoring

Measuring interval can be freely set up by users. Between two measurements the analyzer remains in standby.


Benefits

?  Automatic monitoring system gives alarm signal in abnormal condition. Easy and low maintenance; Low operating cost.

?  4-20mA analog signal output; standard RS232, RS485 digital signal output, MODBUS protocol.

?  New signal processor reduces signal fluctuation to ensure the accuracy and stability of data.

?  Highly precise peristaltic pump extends the service life of pump tubes.

?  Automatic restart when normal power supply after accidental power down.

?  Remote control with local or remote PC connection.

?  Low reagent consumption; short preparation time.

?  Automatic diagnosis function. Identification and alarm for reagent shortage.

?  Instrument operating signal output function.

?  3000 groups of data storage and USB download for analysis data and running log.

?  Easy operation, no special training is required.

?  Controllable running of water pump and free setup for the sampling time of the pump.

?  Security management function, automatic record and storage for all control operations. Read-only storage.

?  2-level operation & management authorization: The system administrator can have all system operation and general operators can only perform routine maintenance & operation.


Measuring Principle

    NH3-N: The sample after proper filtration is pumped into the reactor, where R1(phenol, sodium nitroprusside, potassium tartrate and potassium hydroxide) and R2 (sodium dichloro isocyanurate) are injected and heated to 50°C. Sample reacts with phenol, potassium tartrate and sodium dichloro isocyanurate under alkaline conditions (using sodium nitroprusside as a catalyst ). After fully mixing and reaction, the analyzer measures ABS value of blue substances produced by reaction at the specific wavelength, then calculates sample concentration according to the stored calibration data.

    PO4: The sample after proper filtration is pumped into the reactor, where molybdate and antimony potassium tartrate are injected. Then, injecting ascorbic acid into the sample. After fully mixing and reaction, the analyzer measures ABS value of blue substances produced by reaction at the specific wavelength, then calculates sample concentration according to the stored calibration data.

    TN: The sample after proper filtration is pumped into the reactor, where are injected oxidation reagents R1 and R2 and passed through high temperature UV digestion step. The nitrogen and oxygen contained in the sample are converted into NO3-. The sample is diluted by sodium hydroxide solution and then copper sulfate and hydrazine sulfate is added to convert nitrate into nitrite. Add SAA and NED to the sample. After fully mixing and reaction, the analyzer measures ABS value of red substances produced by reaction at the specific wavelength, then calculates sample concentration according to the stored calibration data.
