Accurate enough for lab use, and rugged and portable enough to take anywhere
The Model 9170 achieves very low temperatures, reaching -45°C in normal room conditions. The 9170 is stable to ± 0.005°C over its full temperature range (up to 140°C) and has 160 mm (6.3 in) of immersion depth. With axial uniformity of ±0.02°C and radial uniformity of ±0.01°C, the 9170 delivers exceptional uncertainty budgets and is perfect for a variety of pharmaceutical and other applications. And Metrology Wells are small enough and light enough to go anywhere.
Fluke has combined bath-level performance with dry-well functionality and legitimate reference thermometry
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. Metrology Wells are different. Temperature gradients, loading effects, and hysteresis have been minimized to make the calibration of the display much more meaningful.

Other great features
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. In addition the 9170 comes with an RS-232 serial interface and the Model 9930, Interface-it software. It is also compatible with Model 9938 MET/TEMP II software for completely automated calibrations of RTDs, thermocouples, and thermistors.
Any of six standard inserts may be ordered with each unit, accommodating a variety of metric- and imperial-sized probe diameters.
Built-In Reference Thermometry
Optional proprietary Tweener measurement circuitry available directly in a heat source — Fluke Metrology Wells. This optionally built-in input accepts 100-, 25-, and 10-ohm PRTs. It reads thermometer probes accurately from ±0.006°C at 0°C to ±0.027°C at 661°C, not including errors from the probe. It is compatible with every PRT sold by Fluke Calibration and connects to Metrology Wells via a 5-pin DIN connector. Available on -R models.
