Fluke Calibration 9170 [9170-A-256] Field Dry-Well Metrology Temperature Calibrator with Model 9170-INSA ("A" Insert) and INSX, -45 to 140°C (-49 to 284°F)

The Fluke Calibration 9170A256 Field Dry-Well Metrology Temperature Calibrator with Model 9170-INSA ("A" Insert) and INSX, -45 °C to 140 °C lets you bring lab-quality performance into whatever field environment you might work in. New analog and digital control techniques provide stability as good as ±0.005 °C. And with dual-zone control, axial (or "vertical") uniformity is as good as ±0.02 °C over a 60 mm (2.36 in.) zone.

There are six critical components of performance in an industrial heat source (which the European metrology community explains, for example, in the document EA-10/13): calibrated display accuracy, stability, axial (vertical) uniformity, radial (well-to-well) uniformity, impact from loading, and hysteresis. Fluke Calibration added a seventh in the form of a legitimate reference thermometer input and created an entirely new product category: Metrology Wells..
