Why does the measurement take a long time to become stable on my Hach Polymetron 2582sc Measuring Instruments?

If the measurement of your Hach Measuring Instruments takes a long time to stabilize, it could be due to several factors. The sample temperature might be significantly different from the ambient temperature; automatic temperature compensation works within 0 to 45 °C (32 to 113 °F). There may be an electrolyte leak through the membrane, causing excessive oxygen penetration. Contamination in the electrolyte, possibly from a loose filling screw, could also be the cause. Ensure the electrolyte filling washer is correctly installed with the plastic filling screw, and tighten the screw without excessive force after replacing the electrolyte. Another cause may be that the electrode is not correctly mounted in the sensor body, so there is a gap between the membrane and the cathode of the electrode...
