  • 0.1° resolution
  • Checks all thermometer types at 0°C (32°F) and 100°C (212°F)
  • Great for refrigerator or freezer probe checks
  • Quick tester to 14°F
  • Accepts all standard probe diameters to 3/8"
  • NIST-Traceable standard
  • Includes 1/8" and 3/16" Inserts

We have the smallest hot unit, and now a cold unit to test thermometers at 0°C (32°F), which is the most common test point for handheld thermometers. With removable and interchangeable test sleeves, you can adapt this mini dry block from 3/8" diameter to 1/8" diameter and only purchase one unit.

  • With a resolution of 0.1°, an accuracy to ±0.5°C, and fast time to temperature, most industrial thermometers can be checked in about 10 minutes. It comes with a NIST Traceable calibration certificate so you can rely on it as a thermometer standard. For even higher precision, use the heat source to perform a comparison calibration with one of our high accuracy thermometry standards. Call us for more details.

    Most thermometers require an accuracy test or calibration at a high and low test point. Our new Sub-Ambient block lets you check your thermometers at 0°C and 100°C in about 10 minutes between test points. You won't find a more versatile calibrator.
