by: EchoLogger

EchoLogger ETF 400S echo sounder with tilt and temperature sensor, harness, and mountings for the drone.

All externally exposed parts, including the cable, are made from PTFE (Teflon), which is fully compatible with low-pH conditions (around pH 2) and even more aggressive acids under normal temperature.

Comes with an RS232 interface and connector for SkyHub.

Please note that additional components and software must be purchased to use this sensor with drones. A full set of required items will be proposed when you request the quote.
