When is the pHoenix meter calibrated?

The pHoenix meter should be calibrated when daily verification indicates that the meter is not within acceptable limits. This is essential because calibration is a process that ensures the meter provides accurate and reliable readings. If routine checks reveal that the meter has drifted from its calibrated state, it must be adjusted to maintain precision in measurements. Regular verification serves as an early warning, allowing operators to address any discrepancies before they affect treatment processes.

Timely calibration based on performance rather than a set schedule, such as weekly or monthly, ensures that the meter consistently meets operational standards. This approach is critical in water treatment facilities, where accurate measurements are vital for compliance with health standards and effective treatment outcomes.
