Microprocessor Photo Colorimeter-1313

Microprocessor Photo Colorimeter 1313 is a compact and easy to operate instrument for Photo Colorimeter analysis of any concentration. The output is available on a 3 digit seven segment red LED display in terms of %Transmission (%T), Absorbance (Abs.), and Concentration (Conc.) and KFactor. This is a unique system that combines convenience with accuracy and precision in analysis.

The instrument includes a wide range of filters covering wavelength from 420-680 nm in the form of in-built filters. The filter setting is controlled by a rotating disc. An in-built shutter control is provided to avoid fatigue of photodiode. When the instrument is switched on, Lamp glows and light passes through the solution to the detector and absorbance or %T measurement is taken. Light source is pre-focused tungsten lamp. The instrument confirms to all general & safety standards.
