CastAway-CTD
$ 0,00
The small, handy CastAway-CTD is a lightweight, easy-to-use instrument designed for quick and accurate conductivity, temperature and depth profiles. Each cast is automatically referenced with both time and location using its built-in GPS receiver. Data can be viewed immediately on its colour LCD screen. The CastAway-CTD is the first handheld castable instrument that provides instantaneous profiles of temperature, salinity, and sound speed. Designed for coastal profiling.
Description
The CastAway-CTD® is the first handheld castable instrument that provides instantaneous profiles of temperature, salinity, and sound speed. Designed for coastal profiling, it incorporates a 6-electrode conductivity cell, coupled with a fast response thermistor to provide accurate, high-resolution data to 100m.
