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.)

Fluke 721 Precision Pressure Calibrator provides pressure calibration and temperature measurement for custody transfer applications



The Fluke 721 Precision Pressure Calibrator is the ideal tool for gas custody transfer applications. It features dual isolated pressure sensors to allow you to take simultaneous static and differential pressure measurements with a single tool. And it can be configured by selecting either a 16 psi (1.1 bar) or 36 psi (2.48 bar) low pressure sensor then adding any of seven high pressure ranges: 100, 300, 500, 1000, 1500, 3000 or 5000 psi (6.9, 20, 24.5, 69, 103.4, 200, 345 bar).



Other useful features:

- Measures up to 30 V DC, checks 24 V loop power supplies

- Extends pressure measurement range with connection to external 750P

- 750 series pressure modules (50 ranges)

- Provides a large backlit graphic display that can show up to three inputs simultaneously

- Stores five instrument setups for recall

The Fluke 64 MAX thermometer has the precision you need to do the job accurately and won't exceed your budget. Designed and tested to withstand a drop of 3 meters, you can count on this compact and lightweight infrared thermometer to work when you need it in the harshest environments and when you can't get near it.

A versatile and rugged tool for high current applications



Confidently take reliable readings with true-rms, Fluke 355 and 353 digital clamp meters; the tool of choice for high current clamp-on amp meter sizes up to 2000 A. The extra wide jaws easily clamp around large conductors, which are typically found in high current applications. The extra robust design and CAT IV 600 V, CAT III 1000 V ratings add an extra element of user protection when performing high power measures.



Accurate peak measurements are possible using the in-rush inrush mode, ideal for motor and inductive loads. The 355 also measures voltage and resistance, making it an ideal clamp meter for utility, electrical contractors and industrial service technicians.
