Simple Enclosure is Waterproof to 400 Metres

Abstract

David Gibson describes a low-cost equipment housing for underwater use at depths of, potentially, up to 1000m although caving applications would normally be at a shallower depth of under 100m. Possible uses of this housing would be as part of a data-logger designed to monitor water depth (via a pressure sensor), as well as temperature, electrical conductivity and possibly turbidity and fluorescence.
