Fluke Calibration 5901B-G Triple Point of Water Cell

Overview

The Fluke Calibration 5901B-G is a mini triple point of water (TPW) cell designed for precise temperature calibration. Using Vienna Standard Mean Ocean Water isotopic composition, the TPW cell provides the most accurate and fundamental temperature standard available. It is simple to use, inexpensive, and achieves uncertainty better than ±0.0001°C, making it ideal for validating SPRTs and performing high-accuracy calibrations of RTDs and PRTs.

Key Features

• Uncertainty better than ±0.0001°C
• Triple point of water standard (most fundamental temperature reference)
• Vienna Standard Mean Ocean Water isotopic composition
• Easy realization and maintenance
• Realization takes only 5 minutes with plateaus lasting all day
• Compatible with Fluke 9210 Maintenance Apparatus for automation
• Mini cell design for simplified procedures and reduced costs
• Nearly equivalent uncertainty to full-size fixed-point cells
• Suitable for use with short immersion probes (9+ inches)
• Perfect for validating SPRT accuracy between recalibrations

Applications

• High-accuracy calibration of RTDs (Resistance Temperature Detectors)
• High-accuracy calibration of PRTs (Platinum Resistance Thermometers)
• SPRT (Standard Platinum Resistance Thermometer) verification and validation
• Comparison calibrations with SPRTs
• Temperature standard maintenance and verification
