HOBO MX800 Bluetooth Multiparameter Water Data Loggers

SKU: MX801 / MX802

Highly versatile, modular wireless multiparameter loggers that integrate sensors (purchased separately) for measuring water conductivity/salinity, depth, temperature (CT/CTD), and dissolved oxygen.

Overview

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.

Features

  • Compatible with interchangeable Conductivity, CTD (conductivity/temperature/depth), and DO sensors (sold separately) – swap out sensors for different applications
  • Bluetooth, for easy logger configuration and data offload
  • Easy to deploy, fully submersible (MX801)
  • Direct read for convenient data offload (MX802)
  • Logger diameter is less than 2 inches
  • Faster data offload via Bluetooth 5.0
  • Water detect feature indicates when logger was out of the water (MX801)
  • Barometric pressure sensor included (MX802)
  • Connect two sensors to one logger to get measurements like salinity adjusted DO directly, with no need for post-processing
  • Guided calibration ensures accurate data
  • User-replaceable batteries
