Features
1.The instrument has variable wavelength and four scales: transmittance absorbency concentration and factor.
2.Using universal test tubes or cuvette to make measure directly.
3.The instrument is micro computerized and easy in operation.
4.The 12nm spectral slit width provides the sensitivity required  for almost any application.
5.One solid-state silicon detector covers entire wavelength range, eliminating the need to change detectors between different  analysis.
6.It is easy to replace the unit of instrument specially the Unit of the Pre-adjusted light source, and make it convenient to maintain.
7.Free adjusting for filter exchange.
8.The grating and toroidal mirrors are selected in optical system。

How to select the test tube
Generally the round test tube is not for optic purpose unless it is pre-checked strictly.
We can select it as follow:
1. Check size. (The size should be f12+0.4×100 mm)
2. Check the surface of tube. (It should be no bubbles, no scabs, no thread like things.)
3. Warming instrument according to §4.2.1.1 ~ §4.2.1.6 and set the wavelength at 360 nm.
4. Pour some pure water into tube and insert it to the test tube well in sample apartment. Check it just as §4.2.1.7. Then put some mark on the tube opposite the white mark at the instrument.
5. Put the other test tube into instrument one by one and get the readout for everyone and put mark at everyone. We can divide them in many groups. In each group the differential of readout for every tub is less then ±0.02A.
6. Then we can use tubes in same group for blank, sample, and standard solution needn’t check the tube every time.
