HOBO MX800 Series multiparameter wireless data loggers work with interchangeable sensors to provide a highly configurable solution for monitoring water conductivity/salinity, temperature, depth, and dissolved oxygen. Available in both an easy-to-deploy, fully submersible model (MX801) and a direct read model (MX802) for convenient data offload that doesn't require having to remove sensors from the water.
