Dissolved Oxygen Meter Uses and Functions

A dissolved oxygen meter is an absolutely essential tool. Any industry that takes an active interest in the quality of its surrounding water will use one of these tools on a regular basis. Oxygen is an essential component to all living things, and a lack of oxygen within a water source could mean certain death to various animals and important bacteria. With the use of this device, anyone can take the necessary steps to ensure that their waterways maintain a healthy balance for animal life.

This type of instrument comes in various guises, but they all serve the same purpose. A dissolved oxygen meter measures the amount of dissolved oxygen that is present within a water source. Polarographic sensors emit a certain voltage that can gather data regarding oxygen levels. Galvanic meters are considered to be more accurate, and do not use any electrical current. An optical florescence sensor is considered ideal for any measurements that last a long time. This type of instrument does not use up any of the oxygen when taking readings, nor is it effected by any outside substances. Therefore, it can be used for long periods of time without worry of any aging.

A dissolved oxygen meter can be used by anybody who is concerned with the health of their local water source, but this tool is commonly utilized by certain industries. Fish farmers tend to make good use of this tool as a way to ensure the health of the fish. Adequate oxygen levels will provide enough for the fish to breathe. Water treatment plants use a dissolved oxygen meter to make sure their treatment process is safe and effective. Any company that disposes waste into a water source is normally required by law to limit the amount they dump. This means it would be to their benefit to use a dissolved oxygen meter to make sure the water isn't over polluted.

These instruments can range from $200 to around $1,400. Hanna is a brand that makes a wide range of meters. Among them is the Hi 93732N model. For roughly $250, this model can measure an oxygen range from 0 to 10mg/L. This is a typical polarographic sensor, and comes with a 9 volt battery.

Oakton also produces different models. Their DO 110 model can store up to 100 pieces of data in either Fahrenheit or Celsius. This is a galvanicmeter, and includes a probe for measurement. The display can read in mg/L, ppm, or % saturation range, and can also provide the water temperature range. It retails for about $600, and can be found at most major industrial supply website.

Water treatment, pollution control, fish farming, or any water based career will need to utilize the special functions of a dissolved oxygen meter to make sure their operations remain healthy for all involved.
