Probes and sensors
Fluke Calibration offers a broad range of precision temperature probes designed for laboratory metrology and demanding industrial applications. These probes provide stable, traceable measurements across wide temperature ranges and are available in several sensor types and constructions to match specific use cases.
Key Characteristics
- Accredited Calibration: Each probe is supplied with an NVLAP-accredited, NIST-traceable calibration report and ITS-90 coefficients or resistance-temperature tables.
- Construction Options: Sheaths in Inconel™️, stainless steel, alumina, PTFE, or silicone provide chemical resistance, flexibility, or high-temperature capability as required.
- Measurement Stability: Designs such as fully supported sensing elements or coil suspension minimize hysteresis and drift.
- Compatibility: All probes interface with Fluke Calibration thermometer readouts, including handheld, benchtop, and dry-well systems.
These precision temperature probes serve as secondary or working standards, bridging the gap between primary laboratory standards and routine industrial measurements while maintaining traceable accuracy and long-term stability.
