RBRcoda³ PAR, RBRcoda³ rad PAR and narrow-band radiometers
Product Number：RBRcoda³ PAR, RBRcoda³ rad PAR and narrow-band radiometers
The RBRcoda³ PAR and RBRcoda³ 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 RBRcoda³ PAR sensor provides uniform response to light in the PAR spectral range, while the RBRcoda³ rad is available in a variety of narrow-band light channels and channel widths.
