For most industrial, laboratory, and field applications, the Dwyer 485B Hygrometer should be calibrated annually (every 12 months). Calibration frequency can vary based on company policy, usage conditions, and regulations, but annual calibration is a typical standard for accuracy assurance.

A Dwyer Instruments 485B Hygrometer doesn’t lie—but it will expose lazy calibration. High‑accuracy measurements demand calibration performed by technicians who understand the 485B, the specification limits, and the standards behind them.
Expert calibration verifies performance against traceable references, flags drift before it becomes failure and documents every adjustment. This isn’t box‑checking or sticker‑slapping. Its precision enforced. If your work depends on numbers you can defend, Rogue Calibration helps find the right calibration service provider for you.
