The 21852 is offered for customers who order a new data logger and require calibration validation from an accredited calibration laboratory. When the 21852 is ordered, Campbell Scientific builds and calibrates the data logger, and then sends it to Simco Electronics in Salt Lake City, UT. After Simco receives the data logger, they perform a calibration validation under the A2LA accreditation. Simco also provides a calibration certificate.
