The 9103 reaches temperatures 50°C below ambient, so –25°C is reached under normal ambient conditions. Our competitors like to advertise their units as reaching –45°C when they really mean –45°C below ambient, which typically means it will go to –20°C. Our unit doesn’t require you to work in a walk-in freezer to achieve its full advertised range.

Choose one of three removable inserts sized for probes from 1/16 inch to 1/2 inch in diameter. Insert A handles a full range of probe sizes with a single well of each size. Insert B features two wells each of 3/8, 1/4, and 3/16 inches in diameter for doing comparison calibrations. Insert C has six 1/4-inch-diameter wells for multiple probe calibrations, and Insert D has three pairs of metric sized wells.

A special adapter sleeve is also available for maintaining X Cells in a 9103 Dry-Well.

For work between 50°C and 600°C, the 9103 is one of our most popular instruments. It has a If you’ve been using dry-well calibrators, you know there’s a lot more to a dry-well than its temperature range and stability. Size, weight, speed, convenience, and software are also significant.

Dry-wells need to be portable, flexible, and suitable for high-volume calibrations or certifications. If they’re not, you’ll soon forget about the great stuff the sales rep told you and realize what you’ve really bought.

At Hart Scientific, we use dry-wells 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 you working for your dry-well.

These three units beat every other comparable dry-well 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-wells 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.

Hart 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 they do 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. It’s the best dry-well software in the industry. Regardless of whether you want basic software or a completely automated calibration system, we’ve got what you want. Read about all our great packages.

Every dry-well 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.
