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
QI 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.
QThe 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.
QDoes 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.
