SP 2000UV/UVPC Visible Spectrophotometer
Can you believe? An UV-Vis spectrophotometer costs less than two thousand, but with power on self-testing, automatic wavelength calibration, light source auto- switching, PC controlled, etc. In the past, it might cost several two-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.

| Spectral scanning |
| In the instrument's wavelength range, run spectra scanning for sample according to the setting wavelength range, get the curve of Absorption/Transmittance vs. wavelength to analyze the spectrum characteristic and identify the maximum absorbance peak. User can do spectrum smoothing, peak or valley detecting, and overlap several spectrum curves to do four basic calculations, print and save the data. |
| Note: There may not be special notifications when the technical specification,profile and configuration changed. Please, the products will be in agreement with the real models. |
