Measurement parameters: more than 70 parameters such as COD, ammonia nitrogen, total phosphorus, total nitrogen, copper, iron, nickel, hexavalent chromium, phosphate, nitrite, etc., which can be customized by users.
Repeatability: ≤3%
Optical stability: The absorbance value of the instrument drifts less than 0.002A within 20 minutes
Reading mode: concentration, absorbance, transmittance
Dimensions: Host: 400×310×158mm
Weight: 5kg

It can detect the concentration, absorbance and transmittance of nearly a hundred parameters in water quality, and can store, print, query and upload the concentration value to the computer.
Measurement wavelength can be selected.
In addition to the factory curves, users can add curves, calibrate curves, and store them in the instrument.
The measurement method of the instrument can be straight line method or broken line method. Selecting the broken line method can achieve more accurate measurement of some parameters with poor linearity.
It has a one-key recovery function, which can realize one-key recovery when the factory curve and user curve data records are lost due to accidents.
The instrument can take backup measures for user-calibrated curves and data records, and can perform recovery operations in case of accidental loss.
The instrument comes with various security measures, which can be set to enter passwords for power-on and system settings.
The instrument has its own calibration function, which can be self-calibrated during operation, which can effectively eliminate the drift error caused by long-term use.
The instrument is operated by a 5-inch large-screen color touch screen with a friendly operation interface.
The light intensity can be adjusted, divided into 16 levels, and can be set arbitrarily, which can effectively solve the problem of expanding the measurement range caused by the strength of the signal.
The curve can be queried. In addition to querying the curve equation, you can also query the standard value of each standard substance and the corresponding absorbance, calibration time and calibration personnel number during calibration, and completely reproduce the state during calibration.
When recording query, single item printing or page printing can be performed.
The system has bilingual function and can switch between Chinese and English.
C-type can store 300 curves, D-type 3500; C-type can store 1000 records, D-type 100000.
The optical system is optimized and upgraded (D type), and the measurement system, precision and stability are better.
The parameters containing COD (chromium method), total phosphorus, total nitrogen, and total chromium are equipped with a digestion instrument. For the information of the digestion instrument, see DIS-16B parameters.
