Insights Case Study: When to Perform a Manual Clean
Background Information
- This analyzer was installed in a drinking water application using free chlorine chemistry.
- The customer noticed that the analyzer signal was consistently lower than their reference measurements.
- According to USEPA 334.0, their analyzer signal had to be within ± 0.1 ppm of their reference measurements to stay in compliance.
- After using Cloud Connect® to view and analyze the data, Kuntze Trial Managers instructed the customer to perform a manual clean of their Zirkon® DIS probe.
Results
- Before the manual clean, the analyzer signal (blue) was lower than the reference measurements (green circles).
- On Day 10, the customer removed their Zirkon® DIS probe, manually cleaned it using a granular detergent, and reinstalled it without performing a calibration.
- After the manual clean was performed, the analyzer signal matched the reference measurements.
- This recommendation could not have been made without using Cloud Connect® to visualize the data.
