CTD/STD- model SD208 and optional sensors

– for extended accuracy and wireless communication

The SD208 measures, calculates and records sea water conductivity, salinity, temperature, depth (pressure), sound velocity and water density. Three optional sensors can be added: dissolved oxygen, fluorescence and turbidity. For optional sensors with several sensitivity ranges, the SD208 has auto range capability. Data are recorded in physical units.

Automatic Profiling Buoy APB5

The APB5 is designed for monitoring water quality in coastal waters, fjords, lakes and fish farms. The buoy contains a control unit, CU801B, an Embedded Web
Server, a GSM/GPRS/EDGE or satellite (IMARSAT/Iridium) router, a winch, a short range radio for communication with sensor unit, solar cells and battery pack.

CTD/STD – model SD204 and optional sensors

The SD204 measures, calculates and records sea water conductivity, salinity, temperature, depth (pressure), sound velocity and water density. Three optional sensors can be added, f. example: dissolved oxygen, fluorescence and turbidity. For optional sensors with several sensitivity ranges, the SD204 has auto range capability. Data are recorded in physical units.

Pressure/ Depth Sensors/ Recorders

The TD301/TD303 is precision instruments measuring temperature and depth (pressure) in the sea, lakes, water reservoirs, groundwater, rivers and on R.O.V. etc. Data are recorded in physical units and simultaneously transmitted via an RS232 I/O watertight connector for on-line use.

Water Level Sensor TD 301R

The TD301R is a high precision instrument for recording/ monitoring of water level in the sea, lakes, water reservoirs, and groundwater and in rivers etc. Also measurement of temperature is included. The sensing element is a unique pressure sensor with built-in temperature compensation. A feature that maintain the high accuracy (0.01%) over a broad temperature range (-2 – 40 deg C).

Tide Recorder – model TD304

A high precision instrument for recording/monitoring of tide or water level and also temperature. Optional sensors can be added: dissolved oxygen, turbidity, and fluorescence (Chlorophyll/Rhodamine/CDOM). The TD304 is available as absolute (TD304A) or reference (TD304R with vented cable and On-land-Unit) types. Data are recorded on internal memory and/or transmitted in physical units via an RS-232 I/O water tight connector. The TD304 provides auto range function for multi range

Communication Unit model CU801

The CU801 is a unit for governing data acquisition on measuring stations/buoys in the field. It is based on dynamic web pages that are continuously updated by data from a connected instrument/sensor. The CU801 consists of an embedded web server and network router that communicate on the global GSM network with possibility of using GPRS/EDGE/3G for faster communication.
