The Wave Guardian D1000SMN is a mini-oceanographic device for offshore monitoring, and can be adapted to perform water quality monitoring. Readings can be taken either dependent or independently and the probe will function correctly in fresh, salt or brackish water.

The robust D1000SMN is fully built in composite, withstanding impacts, solar exposure, salt water and corrosion exemplary. Each section is laminated using UV-stabilized, isophthalic polyester resin reinforced with Kevlar* and glass fibers in order to obtain maximum durability, crash resistance and water impermeability. With thicknesses ranging from 5 up to 7mm this structure is rigid durable and reliable.

D1000 can be upgraded with up to 32 sensors, including ADCP, CTD, dissolved oxygen sensors, temperature, pH, etc.

Simplified modular structure and electronics allow for easy upgradability and maintenance.  From low cost energy efficient sensors to high precision devices can be installed to meet specific client needs.

The WG can generate alerts and send them to mobile devices via Wi-Fi or Bluetooth. For monitoring of several devices we can use a radio frequency transmitter to connect large numbers of devices to 1 central server.  This allows for a real time monitoring of dissolved oxygen, salinity, water level, temperature, pressure, position or live video.

The fully composite structure assures a rust free, low maintenance lifespan. No part of the structure requires painting at any stage of the product’s life span. D1000 can be supplied in all I.A.L.A. colors.
