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.)

Key features
• Calibrate up to four tri-clamp sanitary sensors per batch with ± 0.1 °C temperature display accuracy.
• Covers a wide temperature range: 6109A: 35 °C to 250 °C
• 7109A: -25 °C to 140 °C.
• Stainless steel casing that withstands harsh cleaning solutions; it's easy to transport and maintain.

The Amprobe HD160C Heavy Duty Multimeter is designed for professional use in harsh environments. Its made using waterproof construction to prevent dirt, grime and moisture from entering the case and causing inaccurate readings or damaging shorts.



Built with tough, fire-retardant thermoplastic that is resistant to grease and chemical spills and with shock-mounted components that are drop resistant to at least 8 feet, the Amprobe HD160C is unusually rugged and reliable. It has an extended voltage measurement capability of 1500 V DC and 1000 V AC, unmatched by any other line of digital multimeters. The extended voltage ranges can withstand transients up to 12 kV, and it also measures temperature.

Now there is one intrinsically safe digital multimeter (DMM) you can use in IIC (gas), in Zones 1 and 2, and IIIC (dust), Zones 21 and 22. Whether you work in an oil, chemical, or pharmaceutical environment , all the test and troubleshooting capabilities you need are in the most robust and intrinsically secure (IS) Fluke DMM ever made. The Fluke 28 II Ex is also water, dust and drop resistant. You will be equipped to solve all problems, inside and outside the danger zone, without compromising on compliance or measurement performance.
