The Fluke 1550C performs digital insulation testing up to 5 kV, and makes data collection easy through the Fluke Connect™ wireless app. Remote operation lets you spend as little time as possible in potentially hazardous zones. Real-time trending shows a live graph on your phone, rather than a hard-to-read set of changing values. And you can create reports quickly, using pre-designed templates that you can customize with company logos. It’s the perfect tool for preventive or predictive maintenance programs designed to identify potential equipment failures before they occur. And it comes with a three-year warranty and CAT IV 600 V safety rating.

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.
