Zebra-Tech ships Hydro-Wipers all over the world.
This is part of the latest batch, ready for final inspection and testing prior to shipping. These ones will be winging their way to The United States tomorrow where they will be integrated into nutrient sensors. Some sensor manufacturers choose to integrate our Hydro-Wiper directly in their factory, for others it is an add on feature.
Hydro-Wipers are mechanical wipers designed to gently remove biofouling from the sensitive sensor windows of scientific instruments deployed underwater. They are also used on underwater cameras for the same reason.
