        770S
        Ultraviolet-visible spectrophoto-meter

        Features

        • It adopts 7-inch color touch LCD display, which is flexible and convenient to operate.

        • It adopts proportional double-beam monitoring optical path structure, high-performance, low stray light "blazed holographic grating", high-resolution monochromator, and has outstanding measurement accuracy, accuracy, reproducibility and stability.

        • It has a unique automatic adjustment "0" adjustment "100", eight sample pool linkage. It has various advanced functions such as full-band scanning (only applicable to 770S), sub-band scanning (only applicable to 770S), kinetic time scanning, GOTOλ, linear regression, direct reading of concentration, peak and valley detection, etc.

        • Connected to a printer, data printing can be performed, and printing functions such as spectral scanning (only applicable to 770S), fixed wavelength time scanning, and linear regression curves can be realized.

        • Professional power-off protection measures can memorize test data, scan maps, regression equations, and instrument correction values, etc., and realize rapid initialization and enter the test state when starting up. 

        • The instrument uses a high-energy, long-life flange to position the deuterium lamp. Easy to replace, no need for tedious light path adjustment.

        FAQ

        [Q]
        I want to measure the content of heavy metals in water, which UV spectrophotometer is suitable?
        [A]
        YUE FENG 770S UV spectrophotometer is recommended. Wavelength range 190-1100nm covers the characteristic absorption peaks of heavy metals. Precision +/- 0.5% T can ensure detection accuracy, especially suitable for quantitative analysis of heavy metals such as copper and lead in water quality detection.
        [Q]
        The laboratory needs to do a full-band scan to analyze the purity of the drug. What model should I choose?
        [A]
        The 770S model is designed for full-band scanning, supports 190-1100nm full-band and sub-band scanning functions, and can efficiently complete drug multi-component analysis with eight Sample chamber linkage. Its +/- 0.002A Baseline flatness ensures the accuracy of the scanning map.
        [Q]
        Does this UV-Visible Spectrophotometer meet the GB/T26810 standard?
        [A]
        The UV-Visible Spectrophotometer is suitable for GB/T26810. Please consult customer service for detailed application definition.
