Instruments for Measuring Water Quality

There is a massive variety of equipment available for a range of different tasks, given the complicated science of testing for water quality. Below are some of the most popular devices used.

pH Meters

These usually consist of a probe connected to the meter itself, and are used to take readings of the acidity of a body of water.

Dissolved Oxygen Meter

These determine the amount of dissolved oxygen available in a solution, and as such are particularly useful for finding out whether it is suitable for sustaining life.

Biological Oxygen Demand (BOD) Meter

This device measures how much dissolved oxygen is required by organisms present in the water. If there is a deficiency, this is indicative of an imbalance between oxygen present and oxygen required.

Temperature Measuring Devices

The measuring of temperature can vary from the very simple method of using a thermometer to large electronic devices that store a number of reading taken over a period of time.

Conductivity Meter

The conductivity or ability to conduct electricity can indicate all kinds of things about a solution, and therefore this device's applications are myriad.

Flow Meter

These devices are used for measuring the rate of movment, or flow, of a solution. One reading is taken at a given point of the water, and the rate of flow measured at that point.
