Rationale:

● spectrophotometric analysis method is based on analysis of substances of different molecular structure

and selective absorption of electromagnetic radiation created .

● application of electromagnetic radiation in the spectral region typically 330nm ~ 800nm visible spectrophotometer .

Application:

Uses microprocessor control technology, in the visible spectral region of the material for the qualitative and

quantitative analysis , is essential multipurpose routine laboratory analytical instruments , clinical examination,

biochemical , petrochemical , environmental protection , quality control and tertiary teaching laboratories and other

institutions sectors.

Features:

● LCD display with backlight , reading clarity.

● The use of advanced CT -type holographic blazed grating monochromator with a wavelength of high accuracy,

good color , and low stray light .

● The computer measurement systems, high TA conversion accuracy , and automatic adjustment 0% (T)

and adjusted 100% (T), the concentration of direct reading , concentration factor setting , and select the serial

data printer for data printing capabilities .

● readings of high accuracy, good reproducibility and stability .

● Optional printer.

● UVWin7 package ( sold separately ) .

721G-100 spectrophotometer features:

● 721G same type , the main difference is the test sample chamber widened 10cm cuvette available

specifically for measuring the sugar content , power plants, water , chemicals and other low solution .

The main technical indicators:

● Wavelength range : 340nm ~ 1000nm

● Wavelength Wavelength maximum permissible error : ± 2nm

● Wavelength repeatability : ≤ 1nm

● transmittance than the wavelength of the maximum permissible error : ± 0.5% (T)

● Transmittance Repeatability : ≤ 0.2% (T)

● Spectral Bandwidth : 5nm

● Stray light : ≤ 0.5% (T) ( at 360nm place to NaNO2 measurement )
