Can I connect two sensors to one logger at the same time?

Yes. With the optional W-ADAPT-2 2-Sensor Adapter, you can connect any two W-Series sensors (DO, CT, or CTD) to a single MX801 or MX802 logger simultaneously. This allows you to monitor multiple parameters — for example, dissolved oxygen and conductivity — from a single deployment, and can even enable salinity-adjusted dissolved oxygen calculations directly without post-processing.
