ALERT – E.Coli Analyser

ALERT – E.Coli Analyser
The fluidion™ analyzers implement reactions with chemical reagents and bio-reagents, as well as optical analysis, in order to perform microbiological (E.Coli, Total Coliforms), physical and chemical measurements such as the classical water quality parameters (pH, total and free chlorine, phosphates, nitrates, etc), or more complex measurements of certain pollutants. In particular, the fluidion™ analyzers enable complete analysis protocols, allowing the device to obtain the same accuracy as classical laboratory measurements. Different pre-concentration and filtration steps can also be implemented for more complex analyses. All these features come packaged in a small, fully self-contained system.

SBE 56 Temperature Sensor

SBE 56 Temperature Sensor
The field proven sensor measures and records temperature ensuring long term data stability. Depending on the sample recording interval the Hydro-T can collect high quality data for one month to two years before the battery needs to be replaced. While every application does not require the Hydro-T’s high stability this capability preserves the initial calibration accuracy and ensures less frequent (or no) calibrations. For example, if you only need ±0.01°C accuracy, you will not have to calibrate the Hydro-T for at least 5 years. The Hydro-T is based on field-proven Sea-Bird technology. Cutting edge design and manufacturing make extreme accuracy and precision possible, and the world-leading sensor calibration delivers it.

SeaOWL UV-A™ (Sea Oil-in-Water Locator)

SeaOWL UV-A™ (Sea Oil-in-Water Locator)
Sea-Bird Scientific introduces SeaOWL UV-ATM, a new in-situ oil-in-water sensor. Based-upon the highly successful WET Labs ECO sensor, Sea-Bird Scientific has developed an industry-leading oil-detection technology with 5X optical resolution improvement over its predecessor. SeaOWL UV-ATM measures crude oil-in-water using the same UV-A excitation and blue emission wavelengths (370 nm EX/ 460 nm EM) currently used in the ECO CDOM fluorometer. The SeaOWL UV-ATM improves the resolution and range of the ECO with a greater depth of field, optimized electronics and dynamic gain stage modulation. The new dynamic gain provides industry leading sensitivity across a large detection range making saturation unlikely in even the most heavily impacted environments. The compact SeaOWL UV-ATM design also includes chlorophyll fluorescence and 700 nm backscattering measurements to discriminate crude oil from phytoplankton and other natural sources of FDOM.

RADAC WaveGuide, Directional Radar Wave sensor

RADAC WaveGuide, Directional Radar Wave sensor
With an array of three radars the elevations of the sea surface is measured at three positions. Knowing the slopes and the phase relations, the directional spectrum can be accurately calculated. Radac is the only company that brings this technology to the market. The directional system consists of three downward-pointing radars. Depending on the set-up, all are perpendicularly pointed downwards or one/two are tilted. We recommend the three-point array (1) as the optimal set-up (three downward pointing radars). In a line array (2) one radar is tilted, and in a point array (3) two radars are tilted. Wavelengths are optimally monitored with 3 to 30 times the array size. For example, if the radars are mounted five meters apart, the optimal measurements are between 15m and 150m wave length (3-10 sec period). The new WaveGuide is the latest and most technically advanced radar from Radac. This accurate wave monitoring system is an easy to use, reliable and robust device to measure tide, wave direction, wave height and wave period. The new radar is capable of maintaining high level of precision and accuracy in harsh environmental conditions and is particularly suited to marine and offshore installations.

Radar Wave sensor – UPS and Telemetry System

Radar Wave sensor – UPS and Telemetry System
A key requirement at very remote locations is data availability and independence of both the power supply and telemetry systems. The RADAC WaveGuide is a very robust package mechanically and electrically. Data are available via an integral Ethernet port. Wind turbines typically have Ethernet connectivity ashore for monitoring and control of the turbine but these are highly secure connections and adding third party equipment to them is not a simple option. Likewise, the power supply available within the turbine cabin cannot be guaranteed and so a very reliable uninterruptable, renewable supply is required in addition to a telemetry system.

RADAC On Board Shipborne Radar Wave sensor

RADAC On Board  Shipborne Radar Wave sensor
The Onboard wave radar, mostly installed on the bow of the ship, measures the distance to the water surface. The distances measured have to be compensated for the vertical motions of the radar itself. Hence, a motion sensor is incorporated into the radar unit. The WaveGuide Onboard measures the waves the ship actually has to endure. The radar measures the distance to the water surface 10 times per second. In all wind and wave conditions the accuracy for water level is proven to be below 1 cm. The radar itself facilitates data acquisition, data processing, data presentation and remote service. Data will be internally stored on the device and distributed over the network. Any device connected to the (private) network can access the web-based user interface.

GraviProbe Free Fall Penetrometer

GraviProbe Free Fall Penetrometer
The GraviProbe is a free fall impact instrument, analyzing the underwater sediment layers during intrusion. Under its own weight it accelerates and penetrates fluid and consolidated mud layers. The geotechnical and density conditions of the soil layers are determining the probe’s dynamical behavior. The data acquired from on-board accelerometers, inclinometers and pressure sensors is feeding a dynamical model which determines the geotechnical parameters of the intruded medium (depth, undrained shear and). As a result the GraviProbe is able to very accurately distinguish the depth of the fluid mud and consolidated mud layers, even in gassy environments. The high sensor data acquisition rates of up to 2kHz in combination with a low drag housing results in the highest quality profiles at drop rates over 7 m/s. Due to its light weight the probe can be operated manually from a small vessel, platform or quay and is limiting the operational costs. The GraviProbe Rheology provides tip resistance and shear strength. The GraviProbe Soil is similar to the GraviProbe Rheology but has a conus extension to penetrate hard an stiff sediment layers.
