Digital Photo Colorimeter is compact and easy to operate instruments for colorimetric analysis of a solution of any concentration. Output is available on the display in terms of optical density (absorbance). This is a unique system that combines convenience with accuracy and precision in analysis.

This instrument includes a wide range of filter covering wavelength from 400nm to 700nm in the form of built-in-filters. The filter setting is controlled by a rotating disc.

Automatic shutter is provided to avoid fatigue of the photocell. When put the sample Tube light passes through the solution to the photocell and measurement is taken Light source is refocused tungsten lamp.

Salient Features

  • Accurate
  • Direct readout of absorbance Rugged
  • Reliable & easy to operate
  • Long life photo diode detector
  • 1 mL Sample Size
