The 21XL is a retired product, but the 16088 remains available for customers who previously purchased this data logger model. For the -55° to +80°C range, analog accuracies are derated approximately two times over published specifications. Extended Temperature Testing is typically specified at the time of data logger purchase and is first performed before the data logger ever leaves the factory. However, if application requirements change, individual data loggers can also be returned to Campbell Scientific on an RMA (Returned Material Authorization) to determine if they can pass Extended Temperature Testing. Extended Temperature Testing of a previously purchased unit also requires purchase of concurrent recalibration.
