In order to ensure the repeatability and accuracy of experiments, it is necessary to measure the light irradiance using a light power meter before each photocatalysis experiment. Different models of light power meters should be selected based on the light source intensity and spectral distribution.
The FZ-A type radiometer is a portable, auto-ranging test instrument. It employs SMT surface-mount technology and utilizes high-precision, low-power consumption digital chips. The instrument's exterior features a streamlined design, and the detector undergoes strict calibration for spectral and angular characteristics, ensuring stable performance and high versatility. It can be used to measure visible light irradiance.
