Introduction:

The HCOD-3M COD water quality measurement instruments, developed and produced by NANBEI, use advanced cold light source, narrow-band interference technology and microcomputer to automatically process data. The instrument first digests the sample with sealed catalyst, and then measure them by colorimetric method.

Application:

Widely used in drinking water, groundwater, surface water, municipal sewage, industrial sewage, environmental monitoring, colleges
and universities, scientific research institutions and other fields water measurements.

Features

Product Description

1. The analyzer is separated from the digester, which does not affect the stability of the optical system.
2. The analyzer is a cold light source, narrow-band interference optical system, with good optical stability.
3. Both the analyzer and digester are color touch screen with friendly operation interface and display in Chinese and English.
Simple and time-saving operation. The digestion colorimetry does not need to be changed.
4. With multi-point error-free calibration, the digester realizes zero error measurement at the set point, which completely
eliminates the errors caused by the nonlinearity of the temperature sensor in common digesters in the market.
5.The digester has the function of timing reminder, which can automatically shutdown after digestion, and the instrument has the
function of secondary protection. When the temperature of the digester exceeds 200 ℃, the instrument will cut off the power supply
by itself to ensure the safety of the digestion process.

6. It can store 300 standard curves and 1000 measurements, and data will not lose even when power is cut off.
7. The curve can be inquired. In addition to the curve equation, the standard value of each standard substance, the corresponding
absorbance, the calibration time and the number of the calibration personnel can be inquired, and the calibration state can be
completely reproduced

8. Printing function: you can print a single or a whole page results.
9. With USB interface, and can be connected to computer.

10. The instrument has one key recovery function to prevent accidental loss of curve and data.
11. The instrument has its own calibration function, which can be self calibrated during operation, and can effectively eliminate
the drift error caused by long-term use.
