Domestic COD, ammonia, nitrogen, total phosphorus and total nitrogen analyzer

TCNPN-401D COD, ammonia nitrogen, total phosphorus, total nitrogen analyzer

DIS-16B (or optional DIS-20B/25B/36B) digester;

With printing and USB data upload;

Large screen color touch screen, Chinese and English display;

With one-button recovery function;

Used for wastewater testing.

technical parameters

operating principle

The instrument can directly determine the concentration of COD, ammonia nitrogen, total phosphorus and total nitrogen in water samples. COD is rapid digestion optical method; ammonia nitrogen is Nessler reagent method; phosphorus molybdenum blue method; total nitrogen is alkaline potassium persulfate method.

product feature

1.& nbsp; The analyzer is separated from the digester and does not affect the stability of the optical system.

2.& The instrument is a cold light source, narrow-band interference optical system, good optical stability, 16 adjustable light intensity during calibration, arbitrary setting, can effectively solve the problem of measurement range expansion caused by signal strength.

3.& nbsp; Host and resolution instrument color touch screen, Chinese and English display, friendly operation interface, with operation guide help, to explain various functions.

4.& nbsp; You can query the curve. In addition to querying the curve equation, you can also query the standard value and corresponding absorbance of each standard substance during calibration, as well as the calibration time and calibration personnel number, and completely reproduce the state during calibration.

5.& nbsp; With one-button restore function, when the factory curve and user curve data records are lost due to accidents, one-button restore can be realized.

6.& nbsp; The resolver has a multi-point error-free calibration to achieve zero-error measurement of the set point, completely eliminating the error caused by the nonlinearity of the common resolver on the market due to temperature sensors.

7.& nbsp; The digestion instrument has a regular reminder, and can be set to automatically shut down after digestion. The instrument has a secondary protection function. When the temperature of the digestion instrument exceeds 200 degrees, the instrument will cut off the power supply by itself to ensure the safety of the digestion process.

8.& nbsp; In addition to the factory curve * more than 250 curves, the user can add 3500 curves by himself, calibrate the curve, and store it in the instrument.

9.& Up to 100,000 records are stored (including parameter name, concentration, unit, detection time, operator number, etc.).

10.& Print function: you can print the test records immediately or query the records.

11.& nbsp; USB port, can connect to a computer.
