During a recent commissioning visit to a food and agriculture processing facility in southern Manitoba, we found an oxygen analyzer that had been operating for years without ever being calibrated. It was producing a signal, so operations deemed it “good enough.”
Once we calibrated and verified it, confidence in the reading improved immediately.
It’s a good reminder that instrumentation does not always fail in obvious ways. Proper commissioning and follow-up turn a number on a screen into a measurement that operators can rely on.
