Model 9009 is capable of calibrating thermometers at both hot and cold temperatures simultaneously. Model 9009 from Hart Scientific Inc. combines two dry-block units into a single, portable calibrator, eliminating the need for two separate temperature sources for field testing. The cold block achieves temperatures from 5 to 230°F (-15 to 110°C) with calibrated accuracy of I0.2°C and stability of I0.2°C. The hot block covers 95 to 662°F (35 to 350°C) with accuracy of I0.6°C and stability of I0.2°C. A proprietary controller controls both blocks.
