Measures absorbance and transmittance over the entire UV-Vis range (190 to 1100nm +/- 1nm). Ideal for applications using single & multiple wavelength analysis, wavelength scanning, spectral manipulation, time based kinetic/rate determination, and single component analysis of concentration determination. Spectral bandwidth: <4.5nm.

|UV Lamp does not fire, but heating filament is working.|
My DU-520 UV/Vis Spec UV lamp does not fire up, though the warm-up filement glows. I thought it might be that the UV lamp needed replacement. The new UV lamp had the same results. The startup diagnostics passed. No problem with the visible wavelengths and lamp. What would you suggest?
