Overview

The Fluke Calibration 5609-9BNDP is a secondary reference platinum resistance thermometer (PRT) probe designed for precision temperature measurement from -200°C to 670°C. With its small 6.35 mm diameter and short-term stability of ±10 mK at the triple point of water, this probe delivers accurate measurements in minimal immersion depths of 100 mm.

Key Features

  • Temperature range: -200°C to 670°C
  • Short-term stability: ±10 mK at triple point of water
  • Compact 6.35 mm diameter for fast response and reduced stem effect
  • Reference-grade platinum sensor with four-wire connection for low-noise measurement
  • Inconel sheath construction for durability and precision across wide temperature range
  • Available in multiple sheath lengths: 12", 15", 20" (or 300 mm, 400 mm, 500 mm)
  • Optional 90° bend at 9 inches from tip for dry-well applications
