Key features
• Highly accurate, full-featured , easy-to-use single function RTD temperature calibrator
• Measures and simulates 13 different RTD types and resistance
• Measures 4 to 20 mA signals while simultaneously sourcing a temperature signal
• Comes with a magnetic hanging tool designed in for convenient hands-free operation
• Features configurable 0% and 100% source settings for quick 25% linearity checks

Accurate enough for lab use, and rugged and portable enough to take anywhere
• 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
• Temperature range from –45 °C to 700 °C

Every once in a while, a new product comes around that changes the rules. It happened when we introduced handheld dry-wells. It happened when we introduced Micro-Baths. Now we’ve combined bath-level performance with dry-well functionality and legitimate reference thermometry to create Metrology Wells.

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. (That’s 60 mm!) 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 (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. We added a seventh in the form of a legitimate reference thermometer input and created an entirely new product category: Metrology Wells.

(By the way, Metrology Wells are the only products on the market supported by published specifications addressing every performance category in the EA-10/13. Our specs aren’t just hopes or guidelines. They apply to every Metrology Well we sell.)

Now you can work in two places at once. With the Fluke 233 Wireless Remote Display Multimeter, you don't need anyone else to read the display. Standing on ladders, long and complicated test leads, or calling helpers while testing is a thing of the past. Measure safely even if the meter is placed in a hazardous area, in a clean room, or in a moving machine. The Fluke 233 is a tool that will make your job easier.
