  • ★ Using C-T monochromator, precision grating and aspherical mirror optical components, the whole machine base and parts are made of aluminum alloy die-casting.
    ★ Using pre-calibrated light source, replacement is more convenient.
    ★ Manual adjustment of wavelength; using microcomputer measurement system, with accurate T/A conversion, automatic adjustment of 0% and 100%, direct reading of concentration, concentration factor setting and other functions.
    ★ With RS232 serial interface, optional serial printer can print test data directly; or optional special data processing software package, after connecting with PC, data storage, recording, transmission and linear regression can be realized.
    ★ 722SP visible spectrophotometer adopts flame-retardant insulating all-plastic casing, which is safe to use, small in size and light in weight.
    ★ 722SP visible spectrophotometer adopts reasonable structure and advanced optical system design, adopts high-quality C-T monochromator and sealed grating which are precisely machined, with small size and good optical performance.
    ★ The sample room accommodates 4-position cuvette racks, optional 1-5cm optical diameter rectangular cuvette and 5cm cuvette rack.

  • Instrument introduction:
