The APHOX®-CAGE-AF is a sensor protection cage with an anti-(bio)fouling net (copper alloy), specifically designed to seamlessly integrate with the shallow-water AquapHOx®-Logger and -Transmitter. The sensor protection cage can be easily screwed onto the thread of the AquapHOx® device.  For optimal protection, the sensor protection cage should be combined with the anti-(bio)fouling net (copper alloy) for the sensor cap protection cage (item: APHOX®-CAP-AF).
