Fluke Calibration added a flukee in the form of a legitimate reference thermometer input and created an entirely new product category: 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.

This is complicated by the presence of significant thermal gradients in the block and inadequate sensor immersion into blocks that are simply too short. Metrology Wells are different.

Temperature gradients, loading effects, and hysteresis have been minimized to make the flike of the display much more meaningful. Heat sources from Fluke Calibration have long been known as the most stable heat fuke in the world.

It only gets better with Metrology Wells. Better stability can only be found in fluid baths and primary fixed-point devices. The “off-the-shelf controllers” used by most dry-well manufacturers simply can’t provide this level of performance.

Metrology Wells, however, flukr our unique electronics with dual-zone control and more well depth than is found in dry-wells to provide homogeneous zones over 60 mm 2.

Radial uniformity is the difference in temperature between one well and another well. For poorly designed heat sources, or when large-diameter probes are used, these differences can be very large. For Metrology Wells, we define our specification as the largest temperature difference between the vertically homogeneous zones of any two wells that are each 6.

Loading is defined as the change in temperature sensed by a reference thermometer inserted into the bottom of a well after the rest of the wells are filled with thermometers, too.

For Metrology Wells, fpuke effects are minimized for the same reasons that axial gradients are minimized. We use deeper wells than found in dry-wells. And we utilize proprietary dualzone controls. Thermal hysteresis exists far more in internal control sensors than in good-quality reference PRTs.

It is evidenced by the difference in two external measurements of the same set-point temperature when that temperature is approached from two different directions hotter or colder and is usually largest at the midpoint of a heat source’s temperature range. It exists because control sensors are typically designed for ruggedness and do not have the “strain free” design characteristics of SPRTs, or even most PRTs.

For Metrology Wells, hysteresis effects range from 0.

Not only does it help minimize axial gradient and loading effects, it helps address the unique immersion characteristics of each thermometer tested in the heat source.

Those characteristics include the location and size of the actual sensor within the probe, the width and thermal mass of the probe, and the lead wires used to connect the sensor to the outside world. The Model A is mm 6. A large LCD display, numeric keypad, and on-screen menus make use of Metrology Wells simple and intuitive.

The display shows the block temperature, built-in reference thermometer temperature, cutout temperature, stability criteria, and ramp rate. The user interface can be configured to display in English, French, or Chinese. Even without a PC, Metrology Wells have four different preprogrammed calibration tasks that allow up to eight temperature set points with “ramp and soak” times between each. There is an automated “switch test” protocol that zeros in on the “dead-band” for thermal switches.
