Double your strength



The Fluke 787 was the first device to combine a DMM and a loop calibrator to give process technicians double the power in one tool. Now even better, range is extended in the Fluke 789 – the ultimate loop calibration multimeter. The Fluke 789 has a 24-Volt supply loop which eliminates the need to take a separate power supply when testing transmitters offline. And with selectable onboard 250-Ohm Hart® resistors, the need to carry separate resistors is eliminated. Now process engineers can do more while carrying far less.

High performance furnace for thermocouple calibrations to 1200 °C

The Fluke Calibration 9118A Thermocouple Calibration Furnace is a horizontal, open-ended tube furnace with a temperature range of 300 °C to 1200 °C. It is used for comparison calibration of noble and base-metal thermocouples by secondary high-temperature labs and instrument shops in industries such as aerospace, automotive, energy, metals, and plastics. The 9118A is the most accurate, reliable, and flexible furnace in its class, meeting the demanding requirements of high-temperature thermocouple calibration.

The Fluke 376 Clamp Meter offers improved performance for a wide range of flow size situations. With true-rms voltage and current rating, the Fluke 376 can read up to 1000 V and 1000 A in both ac and dc modes.



In addition, the Fluke 376 includes an iFlex™ flexible current probe that extends the measuring range to 2500 A ac while providing increased display flexibility, the ability to measure odd-sized conductors and increased cable access. The Fluke 376 is a direct replacement for the Fluke 337 Clamp Meter.

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.)
