Discover our mini heat sources, designed to quickly and accurately verify your thermometer's performance up to 250°C/ 482°F. Simply set the heat source to your desired test point, insert the probe, and confirm accuracy in minutes!
With a 0.1° resolution, ±0.5°C accuracy, and rapid temperature stabilization, most industrial thermometers are calibrated in just 10 minutes. Plus, it includes a NIST-Traceable Calibration Certificate, ensuring reliable results as a thermometer standard.
Choose from two block configurations to fit your probe diameters. For even greater precision, perform comparison calibrations using our high-accuracy thermometry standards. Insert your calibrated standard into one of the test wells and your daily-use probe into another test well to compare its performance at any temperature from ambient to 482°F.
Compact and portable, this dry block fits in your hand or toolbox—making it the ultimate calibration tool for most temperature ranges.
