Fluke 9170

The Model 9170 achieves the lowest temperatures of the series, 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, this model delivers exceptional uncertainty budgets and is perfect for a variety of pharmaceutical and other applications.

Fluke 9171

If you need more depth, the Model Fluke 9171 provides 203 mm (8 in) of immersion over temperatures from –30 °C all the way to 155 °C with a full-range stability of ±0.005 °C. Just like the Fluke 9170, this dry-well has exceptional axial and radial uniformity. The display of the Fluke 9171 is calibrated to an accuracy of ±0.1 °C over its full range.

Fluke 9172

The Model Fluke 9172 provides temperatures from 35 °C to 425 °C with a calibrated display accurate to ±0.2 °C at 425 °C. In addition to exceptional accuracy, the 9172 is stable from ±0.005 °C to ±0.01 °C, depending on temperature. With 203 mm (8 in) of immersion, the Fluke 9172 significantly reduces stem conduction errors at high temperatures.

Fluke 9173

For work between 50 °C and 700 °C, the Model Fluke 9173 provides unmatched performance. The Fluke 9173 has a display accuracy of ±0.25 °C at 700 °C and an immersion depth of 203 mm (8 in). Stability and uniformity performance of this unit is enough to dramatically reduce uncertainty budgets for calibrations of thermometers at high temperatures.
