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.

The 3004 has a unique block configuration. It includes a pre-drilled well for a 1/8" (3.3mm) reference probe and then a removable sleeve to size your probe to any size from 1/8" (3.3mm) to 3/8" (9.6mm) diameter. No other dry-well this size gives you this flexibility. 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.

Check out our new mini heat source to check your thermometer's accuracy up to 572°F. Simply set the heat source to the desired test point, insert the test probe into the test well, and get a verification of the performance. It's that easy!
