    VIS-723G Spectrophotometer

    FEATURES:

    1 Single beam wavelength scanning in whole wavelength range of 320-1100nm.

    2 Three options for spectral bandwidth selection: 5nm, 2nm and 1nm, made according to customer's need and satisfy the requirements of pharmacopoeia

    3 Standard manual 4-cell holder accommadates cells from 5-50mm and changeable long path length cell up to 100mm.

    4 Optimized optics and electronics design, light source and detectors from the world famous manufacturer ensure high performance and reliability

    5 Rich measurement methods: wavelength scan, time scan, multi-wavelength determination, multi-order derivative determination, double-wavelength method and triple-wavelength method etc., meet different measurement requirement.

    6 Data output can be obtained via a printer port.

    7 Parameters and data can be saved in case of power failure for user's convenience

    8 PC controlled measurement can be achieved via RS-232 interface (USB port) for more accurate and flexible requirement.
