The miniCTD - DR is fitted with Valeport’s unique digital, high stability conductivity sensor, a PRT temperature sensor, and strain gauge pressure transducer. In addition to the measured parameters listed, Salinity and Density values are also calculated by the software.
0 - 80 mS/cm
-5°C - +35°C
10, 20, 30, 50, 100, 300, 400 or 600 Bar
Features a selection of pre-programmed sampling regimes, covering many standard applications. Data may be sampled from 1 to 8Hz, making it suitable for rapid profiling or for continuous measurement at a fixed point.
Regular output from all sensors at 1, 2, 4 or 8Hz
Logs data as the device falls (or rises) by a defined amount through the water column
Operates autonomously, with setup and data extraction performed by direct communications with PC. Also operates in real time, with a choice of communication protocols fitted as standard and selected by pin choice on the output connector:
Up to 200m cable, direct to serial port
Up to 1000m cable
38400 - 460800
8 data bits, 1 stop bit, No parity, No flow control
Bluetooth logger and communication set are available for cable free data recovery (500m rated)
Fitted with a solid-state, non-volatile Flash memory, storing over 10 million lines of data (equivalent to 10,000 profiles to 500m at 1m profile resolution).
