Elevate Your Monitoring with the HOBO MX800 Series DO Sensor

Experience precise dissolved oxygen (DO) and temperature monitoring with the versatile sensor designed for compatibility with HOBO MX800 Series Water Loggers. This interchangeable DO sensor seamlessly integrates with MX800 loggers to measure DO levels and temperature accurately.


Attach it directly to the fully submersible MX801 model or via cable to the direct read MX802 model for hassle-free data retrieval without disrupting sensor placement. When paired with a conductivity or CTD sensor on the MX800 logger, salinity-adjusted DO readings can be recorded directly. The MX802 model calculates DO percent saturation on the spot, while the MX801 model requires a barometric logger data file for post-processing in the HOBOconnect app.


Seamless Integration for Accurate DO and Temperature Measurements


Features

  • The user-replaceable DO cap boasts a lifespan of 2 years or more, ensuring long-term functionality.
  • Experience high-accuracy measurements that maintain precision even without calibration.
  • Obtain salinity-adjusted DO readings directly when paired with a conductivity sensor (W-CT or W-CTD), eliminating the need for post-processing.
  • Access DO percent saturation data instantly, without the requirement of post-processing (when utilised with MX802).
  • Simplify calibration with the provided calibration boot, effectively saving time and effort.
  • Featuring a compact 1” diameter, it is ideal for narrow wells when connected via cable to MX802 above the well.
  • The durable PVC housing is designed to withstand harsh saltwater environments, ensuring longevity and reliability.


Important Information

Requires a HOBO MX801 or MX802 Data Logger, the HOBOconnect app, and a compatible mobile device or Windows computer. System requirements for the app can be found at the bottom of our HOBOconnect software page.
