The smarter way to calibrate thermometers

The Check-Set Thermometer Calibrator Data Logger and the Check-Set Thermometer Calibrator are designed for today’s food safety, industrial processing, and temperature-sensitive industries—where complete accuracy, compliance, and traceability are a must.

Check-Set Thermometer Calibrators: When it comes to verifying thermometer accuracy, the traditional "ice water and boiling pot" method is messy and leaves room for guesswork. Tel-Tru’s Check-Set Thermometer Calibrators provide a cost-effective, portable, and reliable alternative that improves verification speed and ensures consistency that auditors can trust. Learn more.

Check-Set Thermometer Calibrator Data Logger: For facilities looking to eliminate the vulnerabilities of manual record-keeping—which is often slow and prone to mistakes—the Check-Set Thermometer Calibrator Data Logger is the ideal solution. It automatically records time-stamped entries, selected set points, and operator notes. This creates a highly secure, traceable record that supports your compliance programs and protects your business from costly risks like failed audits, product recalls, and even shutdowns.
