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.
