Fluke 9170-F-R-156

Fluke 9170-F-R-156 Dry-wells are typically calibrated by inserting a calibrated PRT into one of the wells and making adjustments.

In short, there are six critical

components of performance in an

industrial heat source (which the

European metrology community

explains, for example, in the document EA-10/13): 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.

(By the way, Metrology Wells are

the only products on the market

supported by published specifications addressing every performance category in the EA-10/13.

Our specs aren’t just hopes or

guidelines. They apply to every

Metrology Well we sell.)

Display accuracy

Dry-wells are typically calibrated

by inserting a calibrated PRT into

one of the wells and making adjustments to the calibrator’s internal control sensor based on the

readings from the PRT. This has

limited value because the unique

characteristics of the reference

PRT, which essentially become

“calibrated into” the calibrator, are

often quite different from the thermometers tested by the calibrator.
