ZPAR Quantum Sensor is mainly used to measure the photosynthetically active radiation of natural light within the wavelength range of 400~700nm. It is simple to use, can be directly connected to a digital voltmeter or data collector, and can be used under all-weather conditions.
The Quantum Sensor adopts a silicon light detector and passes through a 400~700nm optical filter. When there is light, a voltage signal proportional to the incident radiation intensity is generated, and its sensitivity is proportional to the cosine of the direct angle of the incident light.

Why double glass cover design？
The double glass cover is used to reduce the influence of air convection on the radiometer. The inner cover is designed to cut off the infrared radiation of the outer cover itself.
