1、 Measurement principle

Adopting the principle of ion selective electrode, an integrated sensor is composed of a reference electrode, a working electrode, a compensation electrode, and a temperature electrode.

∆ E = E ( I S E ) – E ( R e f )

IIIQ-LabLinkcorrection system

WTWHaving specific technology can ensure that the relative slope of the ion electrode is maintained for a long time95%Therefore, there is no need to frequently calibrate the electrodes. Simply immerse the entire sensor in a pool, take nearby water samples to the laboratory for analysis, and then input the laboratory results into the instrument. This completes the calibration, taking into account factors such as sample composition and background ion intensity, which can ensure good testing accuracy and stability. Combining with usWTWA multifunctional water quality analyzer that only requires oneUThe disk can automatically input laboratory data intoIQIn the system, it is very convenient.
