15841 21X Retested to Extended Temperature (-55° to +80°C)

The 15844 is available only for 21X(L) Microloggers that have previously passed Extended Temperature Testing. The 15841 requires concurrent purchase of the 16535 Recalibration and an RMA (Returned Material Authorization) from Campbell Scientific.

As individual components age, their ability to perform within specifications at temperature extremes diminishes. Therefore, Campbell Scientific can not guarantee that individual units which may have previously passed Extended Temperature Testing will be capable of doing so at a later date. We will take reasonable measures to bring the datalogger into specification, but if many components are thermally compromised, the unit may not pass. The Extended Temperature Testing fee(s) will be applied whether or not the unit passes.
