      Product Presentation

          KLD-C-CODcr 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

          KLD-C-CODcr is based on GB11914-1989 Water Quality-Determination of the Chemical Oxygen Demand-Dichromate Method. Quantified potassium dichromate solution is added into water sample. After high-temperature digestion in strong acidic condition & with silver salt as catalyst, chromateⅥ is reduced to chromateⅢ by oxygen-demanding organics & reducing substances. The decrement of ChromateⅥ is determined by photoelectric colorimetry. The analyzer then calculates the CODcr value of the sample directly by comparing the measured sample value with the calibration curve established by standard sample.
