WCT
W-CT

The Onset W-CT HOBO Conductivity/Temperature Sensor is designed for use with the HOBO MX800 Series Water Data Loggers (not included). The W-CT works with the HOBO MX800 Series Water Data Loggers to measure conductivity and temperature.

  • Wide measurement range for monitoring freshwater/saltwater
  • Centrally located conductivity sensor minimizes effects from stilling wells/protective guards
  • Temperature sensor placement near tip for fast response time
This product is available for shipping to the US, Canada, and Puerto Rico only.
  • Compatibility: HOBO MX800 Series Water Data Loggers
  • 4-electrode conductivity sensor provides wide measurement range for monitoring freshwater/saltwater
  • Conductivity sensor is centrally located to minimize effects from stilling wells, protective guards
  • 1 in. diameter for use in narrow wells (with cable to MX802 above well)
  • Temperature sensor placement near sensor tip for fast response time
  • Specially treated stainless steel holds up in saltwater

The Onset W-CT HOBO Conductivity/Temperature Sensor is designed for use with the HOBO MX800 Series Water Data Loggers (not included). Along with the data logger, this unit requires the HOBOconnect app and a compatible mobile device or Windows computer for full usage.

The W-CT is an interchangeable sensor that works with HOBO MX800 Series Water Data Loggers to measure conductivity and temperature. With this sensor attached to a HOBO MX800 Series Water Data Logger, the logger can calculate specific conductance, salinity, and total dissolved solids (TDS).

The W-CT can be directly attached to the fully submersible MX801 model. Additionally, this unit can be attached via cable to the direct read MX802 model which does not require having to pull the sensor out of the water to download recorded data.
