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. Available with up to 64Mbyte memory and internal battery pack, as well as a selection of real-time output formats, the CTD+ may be used with Valeport’s own water bottle carousel.
Fitted with CTD sensors as standard, plus your choice of optional additional sensors, either remote or bulkhead mounted. The CTD+ can also operate with Valeport’s water sampler system.
Using the concept of distributed processing; each sensor has its own microprocessor to control sampling and calibration of readings. Each is then controlled by a central processor, which issues global commands and handles all data. This means that all data is sampled at precisely the same instant, giving superior quality profile data. It also allows additional sensor to be added or replaced in the field, without the need for factory recalibration.
Fitted with 16Mb solid state non-volatile FLASH memory. Capacity depends on sampling mode; continuous & burst modes have a single time stamp at the start of the file, trip mode (profiling) stores a time stamp with each reading. The examples are for CTD and 3 other parameters.
The instrument will operate autonomously, with setup and data download using a PC. It can operates in real time, with a choice of comms protocols for a variety of cable lengths, all fitted as standard and selected by pin choice on the output connector:
System is supplied with DataLog Pro PC software, for instrument setup, control, data download and display. DataLog Pro software is licence free
In addition to the standard Conductivity, Temperature and Pressure sensors, additional sensors available are, but not limited to, the following: · Turbidity · pH Sensor · PAR · Redox (ORP) · Transmissometer · Chlorophyll Fluorometer · DO Sensor (Clark Cell \ Optical) · Water Sampler interface Contact Valeport for specific information on optional sensors and configurations
