With groundbreaking new proprietary electronics from Fluke Calibration's (patents pending), Metrology Wells let 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.

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.

• Best-performing industrial heat sources (accuracy, stability, uniformity) in the world
• Immersion depth to 203 mm (8 in)
• Optional ITS-90 reference input reads PRTs to +/- 0.006 °C
• Four models cover a temperature range from -45°C - 700°C
