Visible Spectrophotometer FM-VS-A101
Visible Spectrophotometer FM-VS-A101 is a single beam visible spectrophotometer with large LCD display screen and 4 cell holder capacity. It has wavelength in range of 325 nm to 1000 nm with 4 nm spectral bandwidth and 0.8 nm wavelength repeatability. It uses silicon photo diode detector and tungsten lamp as light source which provides the best wavelength coverage across the working range of the spectrophotometer. This single beam spectrophotometer has highly stable optics with 1200 lines/mm grating. System save test results up to 200 group data and 100 standard curves.
