|Request NIST-Traceable Certificate|
Welcome to the iButton data logger Certificate of Validation web application. This application, supporting the DS1921G-F5N#, DS1922L, DS1922T, DS1922E, and DS1923 (temperature portion only) data loggers, generates validation certificates for individual data loggers or lists of data loggers. The certificates declare that performance accuracy specifications* of the data loggers have been met over the stated range and have been validated on the date(s) given. Validations are performed with reference instrumentation that is certified traceable in accordance with the National Institute of Standards and Technology (NIST). Validation equipment certifications are on file at Maxim Integrated, Dallas, Texas, USA.
*For complete accuracy specifications, refer to the Special Features section and the Temperature Accuracy graphs located in the data sheet of the part(s) in question.
