Features Uses microprocessor control technology, the UV-visible region of the spectrum of the material for the qualitative and quantitative analysis, is essential multipurpose routine laboratory analytical instruments. The use of advanced holographic blazed grating monochromator with a wavelength of high accuracy, good color, and low stray light. Large screen with backlit LCD display, browse the measurement data at a glance. Using computer measuring system, TA conversion of high precision, and automatic adjustment 0% T and adjust 100% T, concentration factor setting, concentration direct reading. Readings of high accuracy, good reproducibility and good stability. Optional serial printer and used in conjunction with software UVWin7 expand the use of the instrument function. UVWin7 software package (optional choose).
