- A typical recommendation is every 12 months under normal use. If the probe is used frequently at high temperatures, subjected to mechanical shock, transported often, or used as a critical reference, consider a 6-month interval or after any event that could affect stability.

Our partners provide traceable electrical calibration services to help ensure measurement accuracy, compliance, and continued usability of your equipment.
Quick Overview
- What it is: A secondary reference platinum resistance thermometer (PRT) for precise temperature measurement and calibration.
- Typical use: Working/transfer standard in dry-wells and liquid baths; verifying and calibrating RTDs, thermocouples, and temperature systems with precision readouts.
- Status: Active (fully available and in production).
A Fluke 5609 Secondary Reference Temperature Sensor (PRT doesn’t lie—but it will expose lazy calibration. High‑accuracy measurements demand calibration performed by technicians who understand the 5609, 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.
