HOBO MX801 CTD, 76m (250’) Depth Data Logger

This data logger kit gives you everything you need to deploy this solution for monitoring conductivity, salinity, and depth (CTD). Users still have the flexibility to add further parameters like dissolved oxygen (DO) using our 2-sensor adapter. Also calculating specific conductance, salinity, and total dissolved solids (TDS), this logger records absolute pressure, which is later converted to water level readings by our HOBOconnect software. To compensate for barometric pressure changes, you can use a HOBO MX20L Water Level logger as a barometric reference.  See our FAQ section for more information.
