HOBO MX801 wireless data logger works with interchangeable sensors to provide a highly configurable solution for monitoring water conductivity/salinity, temperature, level, and dissolved oxygen. The HOBO MX801 Submersible Logger is designed to be used with compatible HOBO W-Series sensors to log water parameters such as temperature, conductivity, depth and more. The MX801 logger must be deployed with the sensors attached, as it is not waterproof if sensors are not attached.

The Onset HOBO MX801 wireless data logger works with interchangeable sensors to provide a highly configurable solution for monitoring water conductivity/salinity, temperature, level, and dissolved oxygen.
