LS-C

The Mini Quantum PAR Sensor LS-C is a miniaturized, flat sensor that can be placed close to leaves in small spaces, for example within cuvettes. The LS-C measures photosynthetically active radiation (PAR). The sensor is well suited for light incident perpendicular to the surface between -30° and + 30°.
