产品描述
adopt 2011-2013 The annual UV visible spectrophotometer Three In the first year of the national product quality supervision and inspection inspection.
Characteristic：
Adopt the advanced holographic blazed grating monochromator wavelength, has high precision, good monochromaticity, low stray light.
Super large screen backlit LCD display, the measurement data at a table.
Adopt the computer measuring system, T-A The conversion of high precision, and automatic adjustment 0%T tuneful 100%T The concentration factor, setting, direct reading.
The measurement of high accuracy, good reproducibility and stability.
- optional serial printer and software UVWin7 With the use of expanding the instrument function.
- UVWin7 The software package (optional).
The main technical indicators:
The wavelength range; 200nm ~ 1000nm
The maximum allowable error - wavelength : 2nm.
- wavelength repeatability : = 1nm
The transmission ratio of the maximum permissible error: + (T (0.5%) with NBS930D Determination)
The proportion of complex transmission That is less than or equal to 0.2% (T)
The spectral bandwidth: 4nm
The stray light ((T) = 0.3%: stay 220nm Where to NaI In the determination. 360nm Where to NaNO Two Determination)
- stability: dark current drift: 0.2% (T) /3min Light current drift: 0.5% (T) /3min
