If the temperature drops below -40°C, is that a problem for the CSAT3BH?

The CSAT3BH is calibrated over the temperature range of -40° to +50°C. Contact Campbell Scientific if your application involves a lower temperature requirement.

The instrument will continue to operate outside the calibrated temperature range, until the signal becomes too weak; however, the proper calibration will not be applied to the measurements because the calibration file only spans the specified temperature range.
