Industry best practice typically recommends calibration of surface thermometers annually (every 12 months), or more frequently if the instrument is used in critical applications or harsh environments. You should always follow your organization's quality or regulatory requirements and manufacturer's recommendations.

A PTC Instruments 312FRRL Surface Thermometer doesn’t lie—but it will expose lazy calibration. High‑accuracy measurements demand calibration performed by technicians who understand the 312FRRL, 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.
