Visible Spectrophotometer 340 - 1000 nm 2 nm 721G 

CE certificated

Description

The application for 721G can be found in: quantitative analysis, qualitative material in the visible spectral region, the microprocessor control technology, biochemical examination, clinical examination, petrochemical examination, environmental protection, tertiary institutions teaching laboratories, quality control and other departments. As you can see, there are many appliances for 721G, and that makes it very versatile, and if in any case, you do not need it anymore, you can sell it easily. Due to the fact that monochromatic with a holographic flashing grating is used, the 721G has an advantage of a very high, wave-light precision with a good monochromaticity and very low stray light. The model comes with a back light LCD display that makes reading very easy, even for people with damaged eyesight. The 721G Visible Spectrophotometer has a very high VIS performance between 335 and 1000 nm, and is specially designed for labs and industries. Here are some additional features: it has a RS232 port, which means a printer can be connected and the data can be sent to a PC with special software, Direct concentration read-out and concentration factor setting function, automatic full scale and zero adjustment, precise automatic T/A changeover, computer control system, Automatic switching of tungsten halogen lamp and deuterium lamp.
