Great performance in portable instruments
• Lightweight and very portable
• Accuracy to ±0.25 °C
• RS-232 interface
• Easy to recalibrate

If you’ve been using a dry well calibrator or dry block calibrator for field work, you know there’s a lot more to them than temperature range and stability. Size, weight, speed, convenience, and software are also significant.

A field dry well needs to be portable, flexible, and suitable for high-volume calibrations or certifications. If it's not, you’ll soon forget about the great stuff the sales rep told you and realize what you’ve really bought.

At Fluke Calibration, we use dry well calibrators every day in our manufacturing and calibration work, and we know what makes a dry well easy and productive to use—which is exactly how users describe our series of field dry wells. These dry wells work for you instead of the other way around.

- The Fluke 417D laser meter is accurate, durable, and easy to use—just point and shoot

- Instantly measure up to 40 m (131 ft.) with 1-button point-and-click

- Continuous measurement capable: adjusting as you move closer and farther from your target

- Quickly calculate area (sq feet/meters)

- 1-meter drop tested and IP54 rated: built to withstand rainy or dusty conditions

- Great for interior and exterior applications

Leak detection in refrigeration engineering? Sure thing! The testo 316-3 refrigerant leak detector can detect all the most common cooling agents and locate even the smallest leaks. Complies with all important regulations and norms. One piece of kit you as a refrigerant technician won’t want to be without.

Your advantages
• Can detect all the most common cooling agents: CFCs, HFCs, FCs
• Highly sensitive – detects even the smallest leaks
• Easy-to-use one-button operation
• Complies with specifications for F gases regulations, SAE Code J1627 and DIN EN 14624:2012 standard

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.)
