Rugged dissolved oxygen, for less

In-Situ has introduced the RDO Blue, its newly-redesigned rugged dissolved oxygen sensor that is tough enough to withstand the harshest environments, yet affordable and easy to use and maintain.

RDO Blue uses an EPA-approved method to accurately measure DO and temperature in freshwater or saltwater environments. Ideal for handheld use or long-term deployment, RDO Blue makes the job easier with:

  • A Smart Sensor Cap with stored calibration coefficients.
  • A unique three-layer system to provide unmatched chemical and abrasion resistance
  • Instant Hydrating Conditioning for accurate reading within 90 seconds of going from dry to wet conditions
  • Easy-to-configure Modbus/RS485 interface for easy integration with existing systems
  • Solid Ryton construction for enhanced reliability
