In fact, the water quality detector and Musical Instruments are similar, in the process of use is to be calibrated. Some customers will ask questions after purchasing the instrument, why is the calibration of the water quality detector so important? This chapter water quality online monitoring instrument manufacturers to understand the relevant issues together with you!

The calibration and measurement data of the testing equipment are closely related, and the water quality testing equipment will be interfered with in use, and it is particularly important if the calibration is not cleaned in time! As for the reason for calibration, it is simply to adjust the instrument that has begun to appear error, and the error of the instrument response is inevitable with the push of time. Free and regular calibration is important!

When using calibrated water quality testing equipment, users must use a standard value close to the water quality standard. The further the distance from the standard value, the less accurate the data provided by the instrument will be. The factors that determine the inaccuracy of the results can be called linear features. It generally refers to that with the concentration change, the response of the instrument will change to a certain extent.

But not all instruments and analytes have this linear behavior, and certainly not all are linear within a given range. Often there are differences in linearity, and these are important factors in determining the effective present. If the instrument does not exhibit linear behavior over a certain range, then choosing two alignments that closely surround the expected values will often offset the inaccuracies caused by nonlinearities!

In summary, the concentration and number of points used to calibrate the equipment will have an impact on the results of the water quality detector. Therefore, when we buy, we must not only carefully select, but also pay attention to calibration in daily use.
