DESCRIPTION
The SBE 19plus V2 (Version 2) SEACAT Profiler measures conductivity, temperature, and pressure (depth) and provides high accuracy and resolution, reliability, and ease-of-use for a wide range of research, monitoring, and engineering applications. The pump-controlled, TC-ducted flow configuration minimizes salinity spiking caused by ship heave and allows for slow descent rates without slowing sensor responses, improving dynamic accuracy and resolving small scale structure in the water column. The V2 is the most versatile successor in the line of Personal CTDs begun with the original SBE 19 SEACAT in 1987.
Compared to the previous SBE 19plus, the 19plus V2 incorporates an electronics upgrade and additional features. The V2 has two additional (six total) differentially amplified A/D input channels, FLASH memory is increased from 8 to 64 MB, and one RS-232 data input channel is added. An optional Digiquartz® pressure sensor provides highest-accuracy pressure measurement. Data can be output in XML as well as ASCII and HEX formats. Firmware upgrades can be downloaded through the communications port by the user, without opening the instrument.
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 to a PC and processed later, or can typically be transmitted in real time more than 100 meters to a PC for acquisition and display using SEASOFT software provided (maximum cable length is dependent on the number of auxiliary sensors, sampling rate, 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 (operation time is shorter if powering auxiliary sensors).
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.
The 19plus V2 can operate in moored mode, recording time series measurements at user-programmable intervals. Moored mode is easily configured using setup commands and by removing the profiling T-C Duct and installing optional anti-fouling devices. (If profiling is not needed, the 16plus V2 SEACAT Recorder offers greater moored-mode programming flexibility and a pressure sensor is optional.).
Accuracy, convenience, portability, software, and support; compelling reasons why the 19plus V2 is today’s best low-cost CTD.
