The Hart Scientific 9171 Metrology Grade Dry Well Calibrator provides 203 mm (8 in) of immersion over temperatures from Tone30 C all the way to 155 C with full-range stability of Tone0.005 C. Just like the 9170, this dry-well has exceptional axial and radial uniformity. The display of the 9171 is calibrated to an accuracy of Tone0.1 C over its full range.

A large LCD display, numeric keypad, and on-screen menus make use of Hart Scientific Metrology Wells simple and intuitive. The 9171 display shows the block temperature, built-in reference thermometer temperature, cutout temperature, stability criteria, and ramp rate.
