Features & Configurations
The RBRduo³ C.T | uv and RBRconcerto³ C.T.D | uv offer the same features as our trusted conductivity, temperature, and depth instruments, plus active antifouling. Four UV LEDs illuminate critical sensor surfaces and control biological growth on the conductivity cell, thus maintaining high accuracy measurements during extended deployments in the photic zone.
Optional configurations
- RBRduo³ C.T | uv: conductivity, temperature sensors
- RBRconcerto³ C.T.D | uv: conductivity, temperature, pressure (depth) sensors
