Low power consumption
RBRcoda3 PAR, RBRcoda3 rad
PAR and narrow-band radiometers
The RBRcodaยณ PAR and RBRcodaยณย rad optical radiometers feature a wide dynamic range, optimized cosine response, and excellent low-light detection, making them ideal for both moored and profiling applications. The sensors are easy to integrate into any RBR multi-parameter instrument, or connect directly via RS-232.
The RBRcodaยณ PAR sensor provides uniform response to light in the PAR spectral range, while the RBRcodaยณrad is available in a variety of narrow-band light channels and channel widths.
- Low power consumption
- High accuracy
- Wide dynamic range
- Depths up to 2000m
- RS-232 output
- Compact and lightweight
