Fluke 9210 Triple Point of Water Calibrator

Overview

The Fluke 9210 is a dedicated maintenance apparatus for triple point of water (TPW) cells, which provide one of the most accurate fixed-point temperature references on the International Temperature Scale (ITS-90). The 9210 provides built-in programming for simple supercool-and-shake realization and maintenance of compatible mini TPW cells, enabling users to quickly establish a 0.01°C reference point with minimal uncertainty.

The apparatus features precision-machined thermal blocks with excellent stability and uniformity, suitable for both cell maintenance and direct comparison calibrations. Its robust design and automated operation make it an essential tool for laboratories requiring frequent access to the triple point of water for temperature scale verification and calibration.

Key Features

• Triple point of water realization at 0.01°C with temperature uncertainty of ±0.0005°C
• Automatic supercool-and-shake functionality for quick TPW cell activation
• Two-mode operation: freeze mode for cell preparation and maintain mode for sustained reference
• Compatible with Fluke 5901B mini TPW cells
• Precision-machined thermal blocks for stable and uniform temperature distribution
• Support for multi-hole and custom thermal blocks with 178 mm (7 in) depth capability
• Audible alert notification when freeze cycle is complete
• Ideal for direct comparison calibrations and temperature scale verification

Applications

• Precision temperature calibration and verification
• Temperature scale certification and metrological traceability
