SP-2000UV/2000UVPC UV-Vis Spectrophotometer
An UV-Vis spectrophotometer costs less than ten thousand, but with power on self-testing, automatic wavelength calibration, light source auto-switching, PC controlled, etc. In the past, it might cost several ten-thousand even decuple with these advanced functions. SP-2000UV UV-Vis spectrophotometer takes use of high precision sine mechanism as a wavelength driver. Program control, wavelength accuracy, and the linearity over the full wavelength are obviously better than those of the congener instruments in which gear and rack is used as a wavelength driver, and a gauge dial is used for wavelength display.
