Step-by-step tutorial: Use the Tel-Tru Check-Set® Calibrator Data Logger to verify and recalibrate bimetal thermometers at precise set points with ±0.2°F lab-grade accuracy. Insert the probe, stabilize, read results, adjust the dial if needed, and let the device auto-log time-stamped data for full traceability—no mess, no guesswork, USDA-approved for HACCP programs.
