Details The Fluke dry-well calibrator gives you the performace of a calibration bath, with the portability and accuracy of a dry-well. In addition you can also purchase this model with a built-in reference thermometer for greater accuracy. Standard features include a large LCD display, numeric keypad and intuitive on-screen menus. The display will simultaneously show the temperature of the block, the reference temperature, stability criteria, ramp rate and built-in reference temperature. If using the well ins standalone mode, there are up to four pre-programmed calibration tasks which allow up to a maximum of 8 temperature set points with ramp and soak times between each.
An automated switch test protocol zeroes in on the dead band for thermal switches. These components are calibrated display accuracy, hysteresis, loading, stability, radial and axial uniformity. The Fluke adds a seventh, in the form of a built-in legitimate reference thermometer. Reference Thermometer Built-In On the -R- models, there is a built-in reference thermometer which uses the Fluke propriety Tweener measurement circuitry.
Display Accuracy Fluke Metrology Wells feature a more accurate display, as the factors that can affect the readouts hysteresis, temperature gradients and loading effects have all been minimised by using traceable and accredited PRTs with the proprietary Tweener electronics which ensure consistent and repeatable accuracy.
With the Fluke Metrology wells, unique electronics, dual-zone control and deeper wells combine to provide a homogeneous zone over 60mm. Radial Uniformity This is the difference in the temperature between two wells. The design of the Fluke means you get consistency between them, with the specification being defined as the largest temperature difference between the vertical homogeneous zones of any two wells.
Immersion Depth This is a key factor when it comes to temperature calibration. It helps to minimise the effects of loading and axial gradients, whilst addressing the unique characteristics of the probe under test. There are several models in the range as listed below.
