The RDO PRO DO sensor ships pre-installed on the buoy. The sensor is
rugged, reliable, and designed to deliver accurate DO and temperature
data across a wide measuring range while reducing maintenance
costs. It features the latest optical technology for DO measurement.
The main components of the sensor include:
• Black sensor body
• Removable nose cone
• Optical DO sensing cap
• Thermistor (for measuring temperature)
