Model 200 Analogue Sensor Display Unit
In response to customer demand, Valeport have used many years of experience in the manufacture of display units for their own instruments, to product a Universal Display Unit for use with a wide range of single channel analogue sensors. The Model 200 Display Unit supplies power to and takes in a 0-5v signal sampling the signal at 1Hz. Features such as user settable average period and standard deviation of data make the unit ideal for using such sensors in a real time capacity, offering a new operating dimension in cases where the manufacturer does not make a dedicated real time display. The Model 200 also allows the user to enter their own calibration function and units, and the internal memory option means that data can be preserved for later analysis.

miniCT Probe
The miniCT probe is Valeport latest direct reading Conductivity and Temperature sensor, featuring digital sampling techniques for improved performance, and high strength construction methods to ensure consistent performance and stability under extreme pressure. 500m acetal and 6000m titanium versions available, both with RS232 or addressable RS485 data outputs as standard

miniCTD Probe
The miniCTD is a new profiling CTD from Valeport, designed for short term or budget applications where sensor performance cannot be compromised. Utilising the same Conductivity and Temperature technology available on our larger instruments, the miniCTD runs on a single C cell, and is fitted with a large Flash memory to record several hundred profiles. Supplied with DataLog Express software, the device features a variety of pre-programmed sampling modes for easy setup and operation. Available in both 6000m titanium and 500m acetal versions.
Monitor CTD Profiler
Based on the leading MIDAS CTD Profiler, the Monitor CTD offers excellent performance but in a smaller, lightweight package for shallow water applications. With internal battery pack and large memory, the Monitor CTD is suitable for both self recording operations down to 500m depth, and real time use with a choice of data output protocols.
MIDAS CTD Profiler
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.
MIDAS CTD+ Multiparameter Profiler

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.

MIDAS SVX2 Combined CTD/SVP
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.
MIDAS 400 Customised Data Acquisition Package
MIDAS 400 Customised Data Acquisition System
 The MIDAS 400 (Multi-Input Data Acquisition System) is a more than just a logger - it is a complete sensor control and data acquisition system, customised to each client's individual specifications. At the heart of the system is Valeport's "400 series" processor. A large range of standard oceanographic sensors may be added to the system in a "plug and play" style, using a series of dedicated interface boards. In this way, an individually tailored suite of sensors can be controlled by a single standard software package, providing features such as synchronised sampling, conditional sampling, delay start and secondary calibrations. A choice of standard housing materials is available, including anodised aluminium and titanium, or alternatively shore based or OEM configurations can be supplied.
