The CE Marking identifies this product as complying with all relevant directives in the European Union (EU).

†IMPORTANT: The plastic case will become brittle at temperatures lower than -20°C. If the logger is deployed in a location where the temperature drops below -20°C, make sure the logger remains stationary and is not pulled on or struck. Return the logger to above -20°C before handling.
