Groundbreaking new proprietary electronics in the 9170 Series let you bring lab-quality performance into whatever field environment you might work in.
The 9170 Series (formerly Hart Scientific) feature new analog and digital control techniques to provide stability as good as ±0.005°C. And with dual-tone control, axial (or "vertical") uniformity is as good as ±0.02°C over a 60 mm (2.36 in) zone. Such performance doesn't exist anywhere else outside of fluid baths.
In short, there are six critical components of performance in an industrial heat source: calibrated display accuracy, stability, axial (vertical) uniformity, radial (well-to-well) uniformity, impact from loading, and hysteresis. We added a seventh in the form of a legitimate reference thermometer input and created an entirely new product category: Metrology Wells.
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, the 9170 delivers exceptional uncertainty budgets and is perfect for a variety of pharmaceutical and other applications.
If you need more depth, the 9171provides 203 mm (8 in) of immersion over temperatures from -30°C all the way to 155°C with full-range stability of ±0.005°C. Just like the 9170, the Model 9171 dry-well has exceptional axial and radial uniformity. The display of the Model 9171 is calibrated to an accuracy of ±0.17°C over its full range.
The 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 ±0.017°C, depending on temperature. With 203 mm (8 in) of immersion, the 9172 significantly reduces stem conduction errors at high temperatures.
For work between 50°C and 700°C, the 9173 provides unmatched performance. The 9173 has a display accuracy of ±0.25°C at 700°C and an immersion depth of 203mm (8 in). Stability and uniformity performance of the 9173 are enough to dramatically reduce uncertainty budgets for calibrations of thermometers at high temperatures.
Of course, there's still a place in the world for dry-wells or "dry block" calibrators. In fact, Fluke Calibration makes and will continue to make some of the best performing, portable, fast dry-wells in the world. There's still nothing better for a quick test of industrial temperature sensor performance.
Any of six standard inserts may be ordered with each 9170 Series, accommodating a variety of metric- and imperial-sized probe diameters. Probe sizes are indicated in inches for A, B, and C, and millimeters for sleeves D, E, and F except for 0.25 inch reference holes in E and F.
