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.

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.
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.
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.
Single Monochrome Type UH3900S uses a spherical surface mirror in front of the entrance slit, while the Double Monochrome Type UH3900D uses diffraction grating.
There is an abundant lineup of accessories to accommodate multiple sample and micro sample applications, etc.
The UH3900S/UH3900D provides aberration-corrected concave gratings with a Seya-Namioka Mount for the spectrometer. Both condensing and dispersing functions allow for a bright optical system, but with fewer mirrors so that light loss and aberrations are reduced.
A lineup of two models with different spectrum systems: Single Monochrome (UH3900S) and Double Monochrome (UH3900D).
The Single Monochrome is suitable for a low-concentration sample since sample light energy is stronger compared tothe Double Monochrome. The Double Monochrome is suitable for a high-concentration sample since it can measure high absorbance with little stray light.
