What is the extended operating temperature range? What is it for?
The standard operating temperature range for the Saga™ logger is -20°C to +50°C. The device is not intended for use outside of this temperature range.
The extended operating temperature range for the Saga™ logger is -30°C to -20°C (i.e., lower extended range) and +50°C to +70°C (i.e., upper extended range).
...
Functionality in the extended temperature range is only a backup option in case the temperature goes beyond the standard operating temperature range.

If you intend to track shipments in the lower extended range, please use Saga™ with the PR-T80 probe (i.e., an external temperature sensor). |
How accurate are the measurements in the extended temperature range?
The devices are not calibrated outside the standard operating temperature range.
The calibration points of the devices are correlated with the standard operating temperature range with a calibration accuracy of ±0.5°C to ±1°C.
...
While the logger is in the extended operating temperature range, it is expected to have a temperature accuracy of ±3°C.
How does the device behave in the extended temperature range?
In the extended temperature range, the device operates with limited functionality and reduced performance.
...
Battery capacity: affected, especially in the lower extended temperature range. The device may enter hibernation mode.
...
Full modem functionality: not guaranteed.
The device may not be able to send data to the CMS when in the upper extended temperature range (+50°C to +70°C). To protect the battery in the lower range (-30°C to -20°C), it will not attempt to send data at all.
