The Fluke Calibration 5623B-6-M precision freezer probe is engineered for demanding temperature verification applications. With a measurement range of -100 °C to 156 °C and an accuracy of ±0.05 °C (including calibration uncertainty and short-term drift), this probe serves as a reliable secondary standard for calibrating other process sensors.
Key Features & Highlights
- Exceptional Accuracy: ±0.05 °C over the entire range ensures precise measurements for critical processes.
- Moisture-Sealed Design: Sealed from sensing element to cable end, preventing moisture ingress even at -100 °C.
- Full Immersion Capability: Can be fully immersed in fluids, making it suitable for liquid bath applications.
- Durable Construction: 6.35 mm (0.25 in) diameter, 125 mm (6 in) long Inconel™ sheath withstands extreme temperatures and harsh environments.
- Versatile Use: Ideal for verifying freezers, autoclaves, and other temperature-controlled equipment where a thermo-well is unavailable.
Applications
The 5623B-6-M is perfect for use in pharmaceutical, medical, and industrial settings where precise temperature verification is essential. It is commonly used for calibration of freezers, refrigerators, autoclaves, and environmental chambers, as well as for liquid bath comparisons.
