class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>Several mechanisms cause conductivity measurement drift:<\/p>\n<p><strong>Electrode Polarization<\/strong>: Ionic accumulation at electrode surfaces

electrode&#39;s effective surface area.<\/p>\n<p><strong>Temperature Sensor Drift<\/strong>: The temperature sensor itself can drift, causing incorrect compensation calculations.<\/p>\n<p><strong>Electronic Aging<\/strong>: Amplifiers, reference voltages, and converters age over time.<\/p>\n<p>According to a 2024 study, unmaintained conductivity sensors demonstrate <strong>drift rates of 0.5-3% per month<\/strong>, accumulating to <strong>6-36% error<\/strong> within a year.<\/p>\n<h2><span class=\"ez-toc-section\"
