Tsingtao Unicom-Optics Instruments Co., Ltd.

Visible Spectrophotometer (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.
