Monitor CTD

Product Name:Monitor CTD
Description: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 protocol
