[0002] The self-calibrated multi-parameter water quality analyzer is a multifunctional water quality monitoring device that integrates automated calibration. It can simultaneously measure multiple key parameters of water bodies and is suitable for environmental monitoring, industrial wastewater, drinking water, aquaculture, and other fields. Its core feature is the reduction of tedious manual calibration operations, improving data accuracy and long-term stability. The self-calibration function involves a built-in standard solution or calibration module, which automatically completes calibration through program control. This makes it suitable for long-term unattended monitoring, avoiding human error.
