3001 Dry-Well
Portable Mini Heat Source
Quick check of thermometer accuracy to 572°F

  • 0.1° resolution
  • Small, lightweight heat source
  • Quick tester to 572°F
  • Accepts all standard probe diameters from 1/8" to 3/8" dia.
  • Four block configurations to choose from
  • NIST-Traceable standard
Check out our new mini heat sources to check your thermometer’s accuracy up 572°F. Simply set the heat source to the desired test point, insert the test probe into the best fitting well, and get a verification of the performance. It’s that easy!

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.

Choose from four block configurations to match the diameters of the probes that you need to calibrate. 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.

This little dry block fits easily in your hand and in your tool box. You won’t find a handier calibration tool that covers most all of your temperature range.
