1.1200RS Visible Spectrophotometer 2.Wavelength Range:335nm-1000nm 3.Wavelength Accuracy:2nm Repeatability:1nm 4.USB output

1200RS Visible Spectrophotometer

Model Number:1200RS

Dynamic Range of 335-1000 nm.

Controlled by built-in MCU, displays by two LED screens each with four digits. One displays wavelength value, the other displays transmittance, absorbance, factor and concentration value.

Built-in RS232 digital output, with Specsoft application software based on Microsoft Windows, create working curve with three points used for calculating concentrations.

Auto 0%(T)and 100%(T)function.

Direct-reading concentration by setting concentration factor or setting reference concentration.

Compact construction and modern design.
