AUV CTD, Ultra Low Power Small Design ROV, Gliders, Floats

AUV CTD No Frame

AUV CTD Perfect for AUVs, UUVs, USVs, Profilers, Gliders, ROVs, Floats, etc. 

D2 has now packaged our Ocean CTD into a new design the AUV CTD that can be easily fit into existing vehicle mounts. Equipped with our new hybrid conductivity cell providing closed field precision without a pump. No pump makes our CTD silent and draw less power. These come in standard CTD mode with high speed 32 Hz sample rate and internal memory. Also available is Ultra Low Power CTDs that draw a mere 4mA and provides 2 Hz sample rate. Providing Salinity, pressure, and temperature data in easy to integrate housings for any AUV Platform. 

Built from Delrin Housing with an Oil Filled Conductivity Cell that is extremely rugged. These are built to deploy to any depth on Earth and provide precision where it matters. 

D2 can provide industry leading Fast Delivery Times. D2 with it’s own brand new salinometer can turn CTD calibrations around rapidly in two weeks or less. With rapid deployment of unmanned systems becoming more important, we can supply CTDs rapidly and with our D2 quality standards. Our equipment is built to be extremely rugged to withstand the harshest environments and conditions. 

The AUV-CTD housing with glass filled Delrin has passed pressure testing to 4000 PSI, which means it can be deployed to 2,757 meters. AUV-CTD Pressure Test
