The 19plus V2 samples continuously at up to 4 scans per second (4 Hz) (2 Hz with Digiquartz®), is battery-powered and self-recording, and is commonly used in the field without a computer, recording up to 1000 individual profiles. Data can be uploaded and processed later, as well as transmitted to a PC in real time for acquisition and display using Seasoft software provided (cable length dependent on number of auxiliary sensors, sampling and baud rate, and cable properties). The 19plus V2 can supply power to 7 external sensors and log their outputs with each CTD scan. Nine D-size alkaline batteries provide up to 60 hours of continuous operation when logging C, T, and P at 4 Hz.

The 19plus V2 is easily integrated with an SBE 32 Carousel Water Sampler and is ideal for integration with the SBE 55 ECO Water Sampler. Both real-time and autonomous auto-fire operations are possible with any Sea-Bird CTD / Water Sampler system.

In moored mode, the 19plus V2 records time series measurements at user-programmable intervals (10 seconds to 4 hours). Moored mode is easily configured with setup commands and by removing the profiling T-C Duct and installing optional anti-foulant devices.

The rugged all stainless steel Digibar S was designed for un-tethered sound velocity casting. This configuration frees the probe from its electrical cable making deeper sound speed profiling a much easier and more reliable task.

• Rugged, stainless steel construction
• 500 meter maximum depth
• Records sound velocity, temperature, pressure and time
• Simple Windows based interface

With a 500 m maximum depth capability and storage for multiple casts, the “S’s” flexible design still maintains some of the best features of the popular Digibar Pro. Immediately before the unit is deployed, a simple system of flashing LEDs serves to confirm battery status, pressure sensor status, and overall probe operation. The confirming indicators drastically reduce the possibility of retrieving a deployment only to find that there is no data to show for the effort. Logging parameters are setup via a simple Windows interface communicating through your PC’s USB port. That same port is used to download the results of the cast and to charge the probe’s internal batteries. Cast data (sound velocity, temperature, pressure, and time) are stored internal to the probe in EEPROM. This means that critical measurements are maintained independently from the batteries that power the unit’s time of flight velocity determining circuitry, thereby providing an extra layer of security for the all-important cast results. Accurate, easy to use, rugged and reliable all appropriate descriptors of the Digibar S and the hallmark of Teledyne Odom’s product lines.

The MIDAS CTD (previously known as the Model 606) is Valeport’s premier CTD Profiler. High accuracy sensors (including ±0.01% pressure) and robust titanium design allow reliable operation to 6000m depth, under the harshest conditions

It also features truly synchronised sampling to ensure that all sensors are sampled at exactly the same point during a profile. Primarily for use as a self recording profiler, the MIDAS CTD also has a range of communications options for real time use, and the low power consumption and large memory also make it suitable for longer term deployments.

The MIDAS CTD+ is a revolutionary Multiparameter CTD, with a wide choice of standard sensors.

Featuring Valeport’s latest 400 Series electronics, the CTD+ will sample all fitted sensors at exactly the same instant, at up to 8Hz. Advanced setup software allows a variety of sampling regimes including burst modes, delay starts, and conditional sampling.

With up to 64Mbyte memory and internal battery pack, as well as a selection of real time output formats, the CTD+ is perfect for both profiling or fixed mooring applications. In addition, the CTD+ may be used with Valeport own water bottle carousel.

The MIDAS SVP is the new name for Valeport’s renowned Model 650 Mk2 Sound Velocity Profiler, and it gives the most accurate Sound Velocity Profiles currently possible.

As well as using the world leading digital time of flight sound speed sensor, this instrument also has a ±0.01% pressure sensor, and features Valeport’s synchronised sampling technique to guarantee that all sensors are sampled at exactly the same point during a profile. Titanium construction and a large memory make it suitable for rapid profiling down to 6000m depth.

The MIDAS SVX2 is the latest version of Valeport’s unique instrument. Recognising the conflict faced by users requiring the superior Sound Velocity data from an SVP, but still needing the Salinity and Density data from a CTD, the MIDAS SVX2 combines both technologies to give the best of both worlds.

Now fitted with a 0.01% pressure sensor as standard, the SVX2 also uses synchronised sampling to ensure perfect profiles, and since the digital time of flight SV sensor is the most accurate in the world, it’s also possible to compare the true sound velocity data with that generated by commonly used equations.

The MIDAS WLR replaces the popular Model 730T as Valeport’s Water Level Recorder / Seabed Tide Gauge.

Designed for long or short term deployments in offshore environments, or locations where a traditional shore based tide gauge is impractical, the MIDAS WLR may be moored in line or to the seabed. The standard instrument is fitted with a 0.01% accuracy pressure sensor and acetal housing for up to 500m depth rating, with a deep water titanium housed option also available.

The miniSVS Sound Velocity Sensors use state of the art digital “time of flight” technology to provide the lowest noise, highest accuracy, best resolution sound velocity data available.

Small size and a choice of sensor lengths down to just 25mm make the sensor suitable for a variety of applications, and the optional pressure or temperature sensor adds versatility. There is a choice of data formats to allow interface to existing systems. We will also consider OEM and custom designs.

The Model 803 is designed specifically for use on ROVs and other underwater vehicles, providing real time relative water velocity information for pilots.

It may be fitted to ROVs to provide actual through the water speeds, or fitted to Tether Management Systems to give measurement of local flow conditions. Measurements are updated every second and the ROVLog™ software provides a graphic and data display, and enables data to be logged to disk.
