Fluke Calibration 5609-9BND-A Secondary PRT Probe

Overview

The Fluke Calibration 5609-9BND-A is a secondary reference platinum resistance thermometer (PRT) probe with a 90° bend feature designed for dry-well calibration applications. This variant of the 5609 series delivers exceptional stability and accuracy across a temperature range from -200°C to 670°C. The 90° bend at nine inches from the probe tip allows convenient insertion into dry-well calibrators while maintaining the precision of a secondary reference PRT.

Key Features

• 90° bend at nine inches from the tip for dry-well calibrator applications
• Secondary reference-grade platinum sensor with four-wire connection
• Operating temperature range: -200°C to 670°C
• Short-term stability at triple point of water: ±10 mK
• Inconel sheath construction for durability and precision
• Small diameter minimizes stem effect and improves response time
• Accurate measurements achievable with 100mm immersion depth

Applications

• Dry-well calibrator insertion and temperature measurement
• Laboratory temperature calibration standards
• Industrial temperature measurement in confined spaces
• Precision calibration applications
