Nephelo / Turbidity meter

Model TD - 01 is an accurate and elegant instrument designed for conducting nephelometric and turbidity measurements of suspended particles and colloids in solution. The principle of operation of this instrument is based on the well-known Tyndall effect. A beam of light passing through a turbid liquid being tested, scatters the light which, in turn, is collected at right angles by a Photocell and indicated in a display. The amount of scattered light is proportional to the turbidity of the solution under test. The salient features of the instrument are its simplicity of operation, accuracy and reliability. The instrument is calibrated directly in N.T.U.'S. The power supply to the 6W lamp is stabilized and the amplifier uses IC- circuitry. The components, electronic as well as optical, are mounted in such a way that they are easily accessible for service. The instrument operates on 230V, 50 Hz nominal AC supply and is housed in an elegant two -tone cabinet. The applications of turbidity measurements are vast -in Municipal, Public Health, Sewage Works and in Industrial Establishments for determining quality of water/waste water.
