For data loggers to be effective, the information they provide must be 100% reliable. Their recordings must be extremely precise and the information produced must be highly accurate. So, how do you know if the data logger you are buying or using is indeed reliable? Data logger manufacturers guarantee their accuracy by means of calibration. The standards for calibration are dictated by the National Institute of Standards and Technology (NIST). Consequently, our calibration results are traceable to NIST measurements and standards.


Since the quality of a data logger is determined by its accuracy, range of measurements, and precision, calibration is fundamental. It is how you, the data logger user, know your data logger is taking exact measurements and recording accurate information. Additionally, calibration is equally important to your customers because it validates your own data and ensures the quality of your products or services.

In North America, the calibration of data loggers must be traceable to and certified per the National Institute of Standards and Technology (NIST) standards. All of Evidencia’s data loggers have a calibration process traceable to NIST measurements and standards. See http://www.nist.gov/traceability for more information.

In the European Union, Evidencia's data logger calibration is certified by the French Institute of Weights and Measures, backed by the “Surveillance Committee against Frauds and Unfair Business Practices” (DGCCRF – Direction Générale de la Concurrence, de la Consommation et de la Répression des Fraudes ). Per European regulations, this French certification is valid throughout the entire European Union. Evidencia’s ThermAssure and ThermAssureRF data loggers are certified per European Union Standards.


Proof that a data logger meets calibration standards comes in the form of a Certificate of Conformance. Since all of Evidencia’s data loggers meet NIST and/or European Union calibration requirements, all our data loggers come with a Certificate of Conformance.

In addition, if your company or customers require additional certification, Evidencia can offer you extra support. We can provide supplementary Calibration Certificates, such those required for ISO and HAACP programs, European Union E18150 regulations , or even for specific company mandates. Simply tell us what your specific requirements are and return your data logger to us. We will then provide you with the appropriate Calibration Certificate..
