Thermochron NIST Traceable Certificates

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 Products, 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.

To generate a certificate, enter the ROM ID of each part to be included on the certificate into the field below. Entries can be entered one per line or delimited by commas or spaces. If the 1-Wire® Drivers are installed, and you have an iButton reader attached, devices can be added by touching each one to the reader. Enter the complete 64-bit (16 character) ROM ID for each device. Note: DS1921G-F5N# data loggers manufactured on 04/06/2011 or later will have NIST data associated with them in this database. All other data loggers listed above will have NIST data associated with them if they were manufactured in 2009 or later.
