- A 2-channel sensor with narrow band filters centred at 660nm and 730nm.
- A very popular filter combination important for plant phytochrome studies, and controlling plant responses in mixed lighting conditions.
- The sensor can be purchased with a simple readout meter, which displays the individual 660nm and 730nm readings as well as the ratio of the wavelengths
- Alternatively, the sensor can be purchased with the SpectroSense2 meter and logger together with other sensors
