Product Name:miniCTD
Description: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. s.
