Product Details
Custom Matching
The multi - parameter water quality tester uses light of a single wavelength to pass through the sample to be tested. According to the Lambert - Beer law, the concentration of a certain substance in the sample is calculated by measuring the absorbance value. Some measurement parameters such as pH, electrical conductivity, dissolved oxygen, and temperature are measured by (electrochemical) electrode methods.

It can detect the concentration, absorbance, and transmittance of nearly a hundred parameters in water quality, and the concentration values can be stored, printed, queried, and uploaded to a computer.
The measurement wavelength is automatically selected.
The instrument is operated with a large - screen color touch screen. The operation interface is user - friendly and comes with an operation guide to explain various function operations.
In addition to a maximum of 250 factory - set curves, users can add 3500 curves by themselves, calibrate the curves, and store them in the instrument.
The storage records reach 100,000 (including parameter names, concentrations, units, detection times, operator numbers, etc.).
The instrument's measurement method can be selected as the straight - line method or the broken - line method. Selecting the broken - line method can achieve more accurate measurement for some parameters with poor linearity.
It has a one - key recovery function. When the factory - set curves and user - set curve data records are lost due to accidents, one - key recovery can be realized.
The instrument can take backup measures for the curves calibrated by users and the data records. When accidental loss occurs, recovery operations can be carried out.
The instrument is equipped with various safety measures. Passwords can be set for startup and system settings to avoid misoperations of the instrument settings by other personnel.
The light intensity is adjustable, divided into 16 levels, which can be set arbitrarily, effectively solving the problem of measurement range expansion caused by signal strength.
Curves can be queried. In addition to querying the curve equation, the standard values of each standard substance during calibration, the corresponding absorbance, the calibration time, and the calibrator number can also be queried, fully reproducing the calibration state.
When querying records, single - item printing or page printing can be carried out.
The system has a bilingual function and can be switched between Chinese and English.
