About Oil In Water Monitors

Oil in water monitors are used to detect the presence of hydrocarbons in water. Samples are extracted from a stream or monitored on a continuous basis. Oil in water analysis consists of many different measurement techniques. Fluorescence analysis determines the intensity of radiation (fluorescence) from a sample which absorbs light at a shorter wavelength and emits light at a longer wavelength. Ultraviolet analysis (UV) measures the amount of UV light that a sample absorbs. Infrared (IR) analysis evaporates a solvent from a plate through which IR light is passed, or uses an IR-transparent solvent to read the solvent/oil mix with an IR instrument. Gravimetric analysis measures the dry weight of a contaminant per unit volume of fluid. After the solvent is separated from the water and boiled off in a controlled environment, the residual is weighed on a balance and reported as oil and grease. Colorimetric analysis is based on the principle that the color intensity of a solution is proportional to the concentration of a specific substance. The solvent is separated, but not boiled off. Instead, a colorimeter or spectrophotometer is used to compare the color of the solvent to known standards for the clean solvent and the specific oil to be measured.

Products & Services Related to Oil In Water Monitors

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.

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.

Turbidity Instruments

Turbidity instruments measure the average volume of light scattering over a defined angular range. Both particle size and concentration of suspended solids as well as dissolved solids can affect the reading.

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.
