About Turbidity Instruments

Turbidity instruments measure the average volume of light scattering over a defined angular range. Both particle size and the concentration of suspended solids, as well as the level of dissolved solids can affect the reading. Turbidity is defined as an expression of the optical property that causes light to be scattered and absorbed, rather than transmitted, in straight lines through the sample. Simply stated, turbidity is the measure of relative sample clarity.

Turbidity instruments can measure not only turbidity but also suspended solids. Turbidity is measured in Nephelometric Turbidity Units or NTU, which represents the average volume scattering over a defined angular range. Both particle size and concentration of suspended solids as well as dissolved solids can affect this reading. When measuring suspended solids, the instruments measure concentration, often in parts per million.

Products & Services Related to Turbidity Instruments

Conductivity and Resistivity Meters
Conductivity meters, dissolved solids meters, and resistivity meters are analytical instruments that measure the conductivity, dissolved solids, and/or resistivity of a liquid sample.
Dissolved CO2 Instruments
Dissolved CO2 instruments are analytical devices that measure the amount of carbon dioxide (CO2) dissolved in a liquid sample such as water. They typically include a submerged probe that is covered by a thin organic membrane.
Dissolved Oxygen Meters
Dissolved oxygen meters are analytical instruments that are used to measure the amount of oxygen dissolved in a liquid sample.
Ion Specific Electrode Meters
Ion specific electrode meters are millivolt meters that interface with ion selective electrodes (ISEs). These meters take the potential generated by the electrode and convert it into units of concentration.
Oil In Water Monitors
Oil in water monitors are used to detect the presence of hydrocarbons in water.
pH and Oxidation Reduction Potential (ORP) Instruments
pH and oxidation reduction potential (ORP) instruments measure or monitor pH (relative concentration of hydrogen ions [H+] in a solution) as well as ORP.
Water Quality Testing Instruments
Water quality testing instruments are used to test water for chemical and biological agents, and to measure variables such as clarity and rate of movement.
