Onset HOBO MX800 Series Water Data Loggers

Key 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
