Description
Overview
The Fluke Calibration 5623B-6-S is a precision PRT probe specifically engineered for low-temperature applications. It features complete sealing from the sensing element to the end of the probe cable, preventing moisture ingress when exposed to temperatures as low as -100°C. The entire assembly withstands temperatures across its full operating range (-100°C to 156°C), making it ideal for verification of freezers or autoclaves where a thermo-well is not available.
Key Features
- Sealed construction prevents moisture ingress in cryogenic environments
- Operating temperature range: -100°C to 156°C
- Accuracy: ±0.05°C across full range (includes calibration uncertainty and short-term drift)
- Inconel sheath, 6.35 mm (0.25 in) diameter × 125 mm (6 in) length
- Fully submersible in liquids for immersion bath applications
- Suitable as secondary standard for calibration of process sensors
Applications
- Freezer and cryogenic chamber verification
- Autoclave temperature calibration
- Liquid bath immersion testing
- Secondary calibration standard for thermal sensors
