Automatic ctd profiling buoy/System model APB5 .
The APB5 is designed for monitoring water quality in coastal waters, fjords, lakes and aquaculture installations. The profiling buoy consist of a embedded web based control unit model CU801B, a Wifi Router with GSM/GPRS/4G or satellite IMARSAT router, a winch for profiling , a short range radio for communication with CTD/STD profiler, solar cells and battery pack. All units are waterproof units made of POM and Titanium.
CTD Profiler model SD208
The SD208 measures, calculates and records sea water conductivity, salinity, temperature, depth (pressure), sound velocity and water density.The SD208 is often referred as a CTD/STD or Sound profiler.
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.
CTD profiler model SD204
The SD204 measures, calculates and records sea water conductivity, salinity, temperature, depth (pressure), sound velocity and water density. The SD204 is often referred as a STD/CTD profiler, Sound profiler or Sound velocity probe.
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.
Data acquisition and transmission unit model CU801
The model 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. It also send measured data-files to a defined file server(FTP) based on the intervall selected.
The CU801 consists of an embedded web server and network router that communicates on the global GSM network based on signal level it will switch between GPRS/EDGE/4G(LTE) communication.
Tide/Water level recorder model TD301R
The TD301R is a high precision instrument for recording/ monitoring of water level in the sea, lakes, water reservoirs, 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 maintane the high accuracy (0.01%) over a broad temperature range (-2 - 40 deg C).
Pressure and Temperature sensor model TD301/TD303
The TD301/TD303 are 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 a serial communication (RS232) I/O watertight connector for on-line use.
Enhanced Tide/Water level 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 autorange function for multirange
SAIV cables and bulkhead connectors
SAIV develop and manufactures high pressure cables and bulkheads connectors for Instruments, Sensors, R.O.V and A.U.V.
