Covers a wide variety of analysis needs from liquid samples to solid samples. Line-up of two types that can be selected in accordance with the measuring object and application. For use in a wide range of fields that focus on water quality, the environment, biotechnology, pharmaceuticals, materials, etc.

This product is a PC controlled system.
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.
Single Monochrome Type U-3900 uses a spherical surface mirror in front of the entrance slit, while the Double Monochrome Type U-3900H uses diffraction grating.
