Double Beam UV-Visible Spectrophotometer L9 190-1100 nm


The Double Beam UV-Visible Spectrophotometer is equipped with surge protection, high-capacity memory for storing test results, images, regression equations and correction data, and a quick power-up phase.

For your convenience, the Spectrophotometer is capable of connecting with a dedicated printer to create prints of test results. It can also make prints of draw curves from spectral scanning, fixed wavelength time-based scanning, and linear regression.

Additionally, there is a USB port on the Spectrophotometer, should you decide to connect to a PC or laptop. With the optional UVwin8 software (available to order), you can get an enhanced view of your data.
