The display is calibrated directly in optical density. The power supply is stabilized against voltage fluctuations using electronic regulators. They are easy to operate, accurate and reliable. The colorimeters are operated by passing white light sequentially through an optical colour filter, a fixed opening, and a test-tube containing an unknown solution, whose concentration needs to be determined. The transmitted light from the sample is then detected by a photocell and displayed.  The instruments operate on 230 volts, 50 Hz AC mains supply. The electronic components are easily accessible for better serviceability.
