Features
  • The measurement wavelength is optional.

  • When recording the query, you can do a single print or page printing.

  • The system has bilingual function and can be switched between Chinese and English.

  • C can store 300 curves, D is 3500; C can store 1000 records, D is 100000.

  • Optical system optimization and upgrade (D), measurement system, accuracy, stability.

  • The instrument is operated by 5-inch large screen color touch screen with friendly operation interface.

  • The instrument has a variety of security measures, can set the boot and system setting input password.

  • In addition to the factory curve, users can add the curve, the calibration curve, and store it into the instrument.

  • The instrument can take backup measures for the curve and data records determined by the user, and can be restored in case of accidental loss.

  • The instrument has its own calibration function, self-calibration during operation, which can effectively eliminate the drift error caused by long-term use.

  • The parameters containing COD (chromium method), total phosphorus, total nitrogen and total chromium are equipped with a digestion instrument.

  • With the one-click recovery function, the one-click recovery can be realized when the factory curve and user curve data records are lost due to accidents.

  • It can detect the concentration, absorbance and transmittance of nearly 100 parameters in water quality, and can store, print, query and upload them to the computer.

  • The light intensity can be adjusted, divided into 16 levels, arbitrary setting, can effectively solve the measurement range expansion problem caused by the strength of the signal.

  • The instrument measurement method can be a straight line method or a broken line method. The broken line method can measure some parameters with poor linear accuracy.

  • In order to query the curve query, in addition to the curve equation, you can also query the standard value of each standard substance and the corresponding absorbance and calibration time and calibration personnel number, fully reproduce the state of the calibration.
