KLD-C NO2-N is a fully automatic online analyzer developed by Xiamen Jilongde Environmental Engineering Co., Ltd. The use of imported CPU motherboards, high-precision signal processors, and a simple and stable waterway system effectively reduces signal fluctuations, ensuring data accuracy and stability; The electrical part and water pipeline are completely isolated to ensure that the analyzer can operate stably for a long time. Suitable for various water qualities such as river water, surface water, and industrial wastewater.

characteristic:

1. Stable and reliable

According to the requirements of industrial and environmental online, the electrical part and water pipeline are completely isolated to ensure that the analyzer can operate stably for a long time.

2. Quantitative accuracy

Controlled by the CPU motherboard, the solenoid valve is used for quantitative dosing, with accurate dosing, simple and stable structure, and long service life.

3. Easy to install

The analyzer has passed a series of tests before leaving the factory. During installation, simply connect the reagent tube, sample tube, pure water tube, waste liquid tube, and power cord, and set the parameters to operate.

4. Automatic correction

The analyzer performs calibration based on the calibration time and calibration type set by the user. If the obtained result exceeds the set limit, the original calibration parameters will not be replaced and an alarm signal will be output.

5. Automatic monitoring

Users can freely set the measurement time interval. The analyzer remains in standby mode between two measurements.

advantage:

• Adopting an automatic monitoring system, simple maintenance, automatic alarm in case of abnormalities, low maintenance volume, and low operating costs

• Standard 4-20mA analog signal output, standard RS232, RS485 digital signal output, standard MODBUS protocol

• Adopting a brand new signal processor to reduce signal fluctuations and ensure data accuracy and stability

• Adopting high-precision peristaltic pump design to extend the service life of the pump tube

• After power failure, it has the function of automatically starting when there is an incoming call

• Can be connected to a local or remote PC for remote control

• Low drug consumption and short preparation time

• Equipped with automatic diagnostic function, it can identify whether there is a shortage of medication and issue an alarm

• Capable of outputting instrument operation signals

• Store 3000 sets of data, available for USB download of analysis data and operation record data

• No special professionals are needed, only simple training is needed to operate

• Can control the operation of the water pump and freely set the sampling time of the water pump

• Equipped with security management function, the device automatically records and stores all control operations in a read-only manner

• Having second level operational management privileges, system administrators can perform all system operations, while general operators only perform routine maintenance and operations

Optional configuration:

Dual channel mode

Realize online monitoring of one instrument and two discharge ports

Pharmaceutical refrigeration box

Extend the service life of medication and reduce the frequency of medication replacement

Alarm function

Pure water low limit alarm and waste liquid high limit alarm function

Automatic dilution function

Automatic dilution of high concentration samples

Mini printer

Print data after measurement is completed

Analysis principle:

After filtering, the sample is pumped into the reactor, and sulfonamide and naphthylethylenediamine dihydrochloride are added. After thorough mixing and reaction, the analyzer measures the ABS value of the red substance generated by the reaction at a specific wavelength, and calculates the concentration of the sample based on the calibration data stored in the analyzer.
