Description

The RCM Blue is a self-recording Current Meter that also measures water temperature in salt or fresh water and a battery container with a battery capacity of up to 70Ah.

The Doppler Current Sensor is an upgraded version of the proven SeaGuard ZPulse sensor. The RCM Blue instrument configuration and data retrieval is done via Bluetooth, eliminating the need to open the pressure case for repeated deployments.

RCM Blue has now been upgraded with the possibility to integrate a pressure sensor with a 0,01% accuracy. This simplifies your work significantly, as you will know exactly where you are in the water column.

Stand-alone sensor

Now available as a stand-alone sensor with Wetmatible Connector (DCS Blue). The sensor can also store data on an internal SD card with an RS-232 interface for easy integration.
