Temperature Calibration Standard
Traceable Confidence for Every Critical Temperature Reading
In regulated life science environments, a small temperature error can trigger deviations, rework, and audit pressure. ETS (Ellab Temperature Standard) is our temperature reference standard and reference thermometer, designed to deliver traceable accuracy and simplify temperature calibration across labs, manufacturing, and cold chain operations.

Calibration starts with confidence in the reference. ETS uses a precision platinum resistance thermometer (PRT) and calibrated conversion coefficients to convert resistance into highly accurate temperature readings that support consistent decisions across teams and sites. Each ETS includes a calibration certificate traceable to Teknologisk Institut, Denmark, helping you standardize your temperature calibration standard across operations and documentation.
For streamlined workflows, ETS connects with ValSuite software and, together with the LiquiCal bath, supports an automatic calibration setup that saves time and simplifies execution.

Great customer service and a great product. Ellab sensors have gone above and beyond expectations but through the years no matter how good your product is, it has to adapt. The Ellab team listens to us about what changes would help or what direction our industry is headed and adapt the product to meet our needs. They stay ahead of the curve of progress and that's why we keep coming back.
Improve Calibration Control with ETS Design Built for Daily Use
ETS is designed to keep calibration predictable. Robust construction, clear live readings, and flexible connectivity help teams execute temperature calibration with fewer disruptions, clearer documentation, and stronger consistency across shifts and sites.
To support all-time audit readiness, ETS helps standardize how teams apply a temperature calibration standard across methods, instruments, and locations. With a traceable temperature reference standard in place, calibration decisions become easier to justify in SOPs, deviations, and audit documentation, while supporting consistent temperature calibration outcomes across the full product and process life cycle.
