MQS-B Quantum Sensor PAR from WALZ

The Cosine Corrected Mini Quantum Sensor MQS-B is designed for light measurements in units relevant for plant leaves. Light has been defined with regard to properties of the human eye.

For photosynthesis research, sensors with spectral and directional sensitivity relevant for plants are required.
