SKU UREC384k Category

The URec384k is delivered with a customized DODOTRONIC recording board sampling up to 384kHz set in an acrilic resin canister with PET caps.

The standard hydrophone is a Sensor Technology SQ26-05 pre-amplified hydrophone on one cap.
Several other hydrophones models are available for integration, including the Aquarian Audio H2c, the Aquarian Scientific AS-1 and the whole series of Cetacean Research Technology sensors.

The canister can be delivered with different battery sets, and can go down to more than -500m, depending on the provided hydrophone.

A magnetic switch can be used to start/stop the power supply externally without opening the canister.
A custom preamp has been developed to fit the levels and the output impedance of the hydrophones, providing a no-noise signal to the recorder.

O-rings on each end provide extra resistance to high pressures, while the 1cm wall safely keeps the instrument dry.

Programmable via bluetooth connection and a custom software for your Android phone, can be set to follow a duty-cycle scheme (record for an x period and then pause for a y period) or specific time intervals (record from xx:xx to yy:yy and then again from zz:zz to tt:tt …).

The URec384k, with its DODOTRONIC board, is probably the most flexible acoustic monitoring device on the market.

Battery capacity can deliver weeks of sampling, all stored on the mSD on the board.
A precise RTC (real-time clock) marks the recordings on the filename for later analysis.

A magnetic switch can put the system in stand-by, without opening the canister, while waiting for deployment.
