iSocket is designed to be used in a dry environment. We have tested it down to -30C (-22F) in Finland, but NOTE that the device has a li-ion battery that is not suitable for use at extreme cold temperatures. The device is therefore usually rated to work down to -10C (14F). More details can be found in the Tech Spec tabs for each product on the iSocket World catalog.
