The UH3900 is a low-noise model equipped with a photomultiplier tube (PMT) detector. With the latest software, UV Solutions Plus, it delivers an even more comfortable and user-friendly operating experience. Two types are available to match your measurement needs: single monochromator and double monochromator configurations. From liquid samples to solid samples, the UH3900 series supports a wide range of analytical requirements and is used across diverse fields including water quality testing, environmental analysis, bio/life science, pharmaceuticals, and materials research. Features UV Solutions Plus allows for easy device control and supports various quantitative-analysis functions A new data processing software, the successor to UV Solutions, has been adopted. It offers clear table views for data lists and processing results, customizable report layouts, and enhanced performance verification features. Possible to perform measurements in a wide absorbance range with low stray light and low noise The larger the amount of transmitted light, the lower the noise of the obtained absorption spectrum so that a wider absorbance range can be measured. Measurements of high concentration samples can be performed over a wider concentration range. Stable spectrometer with double beam optical system The light source uses a WI lamp (visible range) and a D2 lamp (ultraviolet range) that switches wavelength depending on the measurement. The double beam system divides the monochromatic light so that the diffraction grates into the control and the sample with a rotational mirror, guiding the light to the sample chamber.
