A spectrophotometer covering wavelengths from 340 to 900 nm measures transmittance, absorbance, and concentration. (It does not cover the ultraviolet region.)
● The optical section, which is the heart of the device, adopts a split beam method. ● Automatically recognizes the optimal cell according to the measurement items, supporting five types of cells. ● Performs an automatic internal check when powered on. ● A portable size spectrophotometer. ● Easily replaceable light source lamp (tungsten halogen lamp). ● Pre-installed with over 96 methods. User methods can also be created up to a maximum of 100. ● Method identification via barcode reader (only for MF2RS-913H). ● Smooth and user-friendly keypad. Equipped with a power adapter as well as a rechargeable battery. ● Data transfer to PC or USB memory is possible in both CSV and PDF file formats.
