Visible Light Transmittance Meter

The visible light transmittance meter emits visible light through a sample, and a sensor receives the intensity of the transmitted light, comparing it with the original light intensity to calculate the percentage of transmittance. It is used to detect the light transmission performance of materials such as plastic films and glass in the 380-780 nm wavelength range, guiding production quality control.
Selection
When selecting, focus on ensuring the measurement wavelength range matches the material characteristics, the accuracy meets industry standards, and a calibration whiteboard is included to guarantee data reliability. Consider the compatibility with sample thickness and the simplicity of the operation interface. Choose between manual or automatic models based on daily testing volume, and ensure the instrument's adaptability to the environment.
