The UV visible detector adopts advanced electronic circuits, holographic concave grating optical path system, and imported key components, with good wavelength accuracy and repeatability. By controlling the sine mechanism with a microcontroller, the grating is rotated to achieve automatic wavelength setting. By using PC control, the time wavelength program can be implemented, and real-time switching of wavelengths can be analyzed online. This can achieve high sensitivity in compound determination and has the function of stopping the pump for spectral scanning.
