Our product experts are here to help you find the right solution for your application!

These two units beat every other comparable dry block calibrator in the industry in performance, size, weight, convenience, ease of calibration, software, and price. In addition, the heating and cooling rate of each of these dry-well calibrators is adjustable from the front panel, thermal switches can be checked for actuation testing, and multiple-hole inserts are available for a variety of probe sizes.


Fluke Calibration dry wells are easy to calibrate - you don’t even have to open the case. This means less maintenance costs and less down time when a dry well does need calibration.


Our Interface-it software lets you adjust set-points and ramp rates, log dry-well readings to a file, create an electronic strip chart, and perform thermal switch testing with data collection. The software is written for Windows and has a great graphical interface. Regardless of whether you want basic software or a completely automated calibration system, we’ve got what you want.


Every dry block calibrator we ship is tested at our factory, and every unit comes with a NIST-traceable calibration. There’s no extra charge for the report, because we consider it an essential ingredient in our quality program. You shouldn’t have to pay extra for calibration procedures we perform anyway.
