The 9144 Field Metrology Well has replaced the 9141 Dry-Well
The Fluke Calibration 9141 Dry-Well is now obsolete and has been replaced with the 9144 Field Metrology Well.
Top reasons to consider the 9144 Field Metrology Well over the 9141 Dry-Well
- Better accuracy, stability, and radial uniformity
- Dual heater zones improve vertical temperature gradient
- Greater immersion depth
- Modern user interface and industrial design
- Process Electronics option to read external reference probes and UUTs
