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.
