Thermal Validation: Matching Tool to Task

Download the complete article.

Synopsis:

This peer-reviewed article explains how the proven stability of Veriteq's thermistor-based data loggers is the key to eliminating pre- and post-calibrations, which allows for unprecedented accuracy and efficiency in thermal validation projects.

Evidence That Stable Sensors Eliminate Pre- & Post-Calibration

As outlined in the article, our A2LA accredited calibration laboratory performed 2,427 routine service calibrations on Veriteq data loggers that had been in field use for 10 to 14 months. Of these devices, 99.7% were returned for calibration well within the original accuracy specifications. Of the eight that were found Out of Specification (OOS), none were out by more than 0.12ºC, and the average OOS value was 0.036ºC.

These results indicate that, with the Veriteq Validation System, skipping pre- and post-calibrations is not reckless practice. The stability of the data loggers allows for a more efficient and accurate validation method. In addition, the reduced set-up and deployment time of our system, along with little or no operational downtime that normally accompanies validating with thermocouple-based sytems, reduces many of the high costs associated with validation.

The article was published in the winter 2008 issue of the Journal of Validation Technology.

We use the veriteq logger system and were initially concerned by the annual calibration in comparison to using the kaye validator system.

We regularly perform calibration checks against our PRT Probes to confirm the units are within calibration and have never found and veriteq logger to be out of specification.

The veriteq system is a reliable alternative to thermocouple based systems and had enabled us to dramatically reduce our validation costs. For more information take a look at our website www.thermalcompliance.co.uk
