Hart Scientific manufactures these Micro-Baths for calibration of thermometers and sensors that do not fit in block calibrators.


  • Rugged, reliable basic True-RMS clamp meter
  • Measure AC current up to 400 A, AC/DC voltage to 600V
  • Measure resistance up to 4kΩ, continuity detection ≤ 30Ω
  • Additions from 323 Clamp: Temperature, Capacitance, Backlight


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. 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 starting on page 80.
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.
