sky technology india Digital photo colorimeter 8 filter /colori meter ( model no STI 404 ) Digital Colorimeter  (400-700 nm)

SKY TECHONOLOGY Digital Photo Colorimeter 8 Filters- mains operated with optical density in 2½ digit LED display, 1ml solution measurement. The basic set-up of the colorimeter is: A. LED light source: Produces polychromatic light over the entire visible region, B. Broad spectrum filter: The colorwheel has eight different filters. The filter employed is selected by wavelength. Each filter will produce monochromatic light at a specified peak wavelength with a bandpass of 20 nm. The filters enable the user to perform tests from 400 to 680 nm. C. Cuvette Holder: It holds the inserted cuvette during testing. It is imperative the cuvette be consistently oriented in the holder. Round cells usually have orientation markings to correctly position the cuvette, D. Detector: A silicon photo diode is used as the detector. The photo detector current will change as a function of light energy. E. Display:The current signa lfrom the detector is converted to a numerical value, absorbance and is shown on LED display.
