Red / Far-Red Sensor

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
