Fluke Calibration 9173 Field Metrology Well

Brand: Fluke Corporation

Every once in a while, a new product comes around that changes the rules. 

It happened when we introduced handheld dry-wells. 

It happened when we introduced Micro-Baths. 

Now we’ve combined bath-level performance with dry-well functionality and legitimate reference thermometry to create Metrology Wells.

With groundbreaking new proprietary electronics from Fluke Calibration's (patents pending), Metrology Wells let you bring lab-quality performance into whatever field environment you might work in. 

New analog and digital control techniques provide stability as good as ±0.005 °C. And with dual-zone control, axial (or “vertical”) uniformity is as good as ±0.02 °C over a 60 mm (2.36 in) zone. (That’s 60 mm!) 

Such performance doesn’t exist anywhere else outside of fluid baths.

In short, there are six critical components of performance in an industrial heat source: calibrated display accuracy, stability, axial (vertical) uniformity, radial (well-to-well) uniformity, impact from loading, and hysteresis. 

We added a seventh in the form of a legitimate reference thermometer input and created an entirely new product category: Metrology Wells.
