In many production environments, conductivity calibration is treated as a routine task – something that needs to be completed to satisfy quality requirements but rarely receives much attention beyond that.
A sensor is removed from the process, sent to a laboratory, calibrated, and reinstalled. Production is stopped, documentation is updated, and operations move on.
Over time, however, this familiar workflow begins to raise questions. Why does calibration require so much downtime? Why do results sometimes differ after reinstallation? And is laboratory calibration always the most appropriate approach for sensors operating continuously in production processes?
There are two fundamentally different methods for performing conductivity calibrations. One method is by using a standard solution with a known conductivity value. The other is by comparison with a reference instrument such as the Insatech Insacal Conductivity Meter described on this site.
When choosing your methodology, you need to take several things into consideration, including accuracy requirements, process conditions, and the impact on production.
