Fluke Calibration 5623B-6-B Precision Freezer Probe, 6.35 mm x 125 mm, -100 to 156 °C

The Fluke Calibration 5623B-6-B is a precision freezer probe designed for accurate temperature measurement in demanding industrial and laboratory environments. This probe is part of the Fluke Calibration Temperature Measurement range and is engineered to deliver reliable performance in low-temperature applications.

Key Features & Highlights

• Sealed construction: The probe is specially sealed from the sensing element to the end of the cable, preventing moisture ingress even at temperatures as low as -100 °C.
• Wide temperature range: Operates over -100 °C to 156 °C, making it suitable for freezer verification, autoclave testing, and other extreme temperature applications.
• High accuracy: Provides accuracy of ±0.05 °C (including calibration uncertainty and short-term drift) over its full range, serving as a reliable secondary standard.
• Durable sheath: Features a 6.35 mm (0.25 in) diameter, 125 mm (6 in) long Inconel™ sheath for robustness and corrosion resistance.
• Fully immersible: Can be fully immersed in fluids, ideal for use in liquid baths.

Applications

The Fluke Calibration 5623B-6-B is ideal for verifying freezers and autoclaves where a thermo-well is not available. It is also well-suited for calibration of other process sensors and for use in liquid bath applications where precise temperature measurement is critical.
