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. 

The Model 9140 has a temperature range of 35°C to 350°C, and it reaches its maximum temperature in 12 minutes. At six pounds, it’s small enough to easily carry in one hand. It’s truly a unique innovation in dry-wells. 

The unit has a stability of ±0.05°C or better and a uniformity of at least 0.4°C in the largest-diameter wells and 0.1°C in the smaller wells. Despite its small size, this unit performs. 

Use the display, calibrated to ±0.5°C, as your reference, or use an external thermometer for maximum calibration accuracy. With three removable inserts to choose from, the 9140 is as versatile as it is fast. 

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 here. 

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.
