Turbidity is used as a water quality indicator, particularly for drinking water. Turbidity meters measure the loss in light beam intensity as it passes through, of a fluid containing suspended particles. Ideally, for a water sample, the suspended particles should allow the incident light to scatter at an angle of 90 degrees with respect to the light source, however, according to the particle size, the angle of light differs. A smaller angle of scatter indicates larger particles and hence a highly turbid water sample. Supplying the calculated loss directly related to light particles scattering and absorbing, the tools come in desktop or portable styles. Boasting advanced features, the devices offer a high degree of ease while employed as well as reproducible results. The turbidity meters transport the collected data to other systems for further review. Turbidity is often measured by Nephelometric Turbidity Unit (NTU) or Formazin Turbidity Unit (FTU) and the dry-weight of suspended materials is indicated by Total Suspended Solids (TSS).
