The Use Of A Dissolved Oxygen Test Kit

By Jennie Sandoval


The dissolved oxygen test kit is not very different from any other checking kits elsewhere in the world. It is an important apparatus in aquaculture. It is employed to assess the quantity of oxygen in a certain sample of water. Their existence a number of this kits that includes; hash D. O., Chemists, Hanna water resistant D. O. Meter are some of the examples of the investigative kits all that determine various aspects of water quality.

All aquatic organisms depend on air which is oxygenated; fish and other aquatic organism are used for respiration and gaseous exchange while plankton removes oxygen as a waste. The natural waters usually contain high levels of air contained in form of solution to create a very healthy and steady environment. A low amount of liquid oxygenated air affects the gaseous exchange process in the fish and the level of ammonia and nitrite toxicity.

Factors affecting the concentration of oxygenated air and other toxic gases such as carbon four oxide, ammonia, nitrite and sulphide are salinity, temperature and availability of oxidizing and reducing agents are minimal. Low temperatures boost the absorption of atmospheric air. That is by the water while high temperatures reduce the absorption of atmospheric air by the water.

The quantity of sampled dissolved air varies depending on the source and region in which the sample is collected. The test kits vary depending on the cost; accuracy and samples available.Air bags tablets are the lifeline of the kit and are well labeled to prevent a mix up, gloves are worn to prevent damage to human skin and small test tube. The procedure for evaluating dissolved air is that tablets are placed in small test tubes containing the sampled water and the mixture is mixed, the color changes observed is compared to a chromatography chart. The atmospheric air within solution checking is measured in parts per million (ppm) or milligrams per liter (mg/l).

The concentration of dissolved oxygen in the tested water differs by far depending on the water body source drawn from. A check bag contains small checking tubes for samples, tablets and a color chart illustrating different range of colors, gloves are usually recommended to prevent any unforeseen injury. The air within solution bag checking is usually calculated in grams per liter or parts per million. Air within a solution not only contributes to respiration only but also to decomposition.

Advantages of using air in solution bag is that it is cheap. It also requires less guidance when using. This enhances scientific innovation.

This enhance scientific invention. As if that is not enough, it makes them very efficient. Also they are accurate and reliable while the disadvantages consist of it being very expensive to buy and use since it is labor intensive and can offer scope for inaccuracy.

The dissolved oxygen test kit significance worldwide is vital for the existence of a stable aquatic ecosystem; the air also determines other factors like the availability of fish in a certain region. Also it is used in waste water treatment and enhances the flavor and shelf life of beer in the beer making industry, drinking water is an essential aspect of nutrition thus keeping it safe and clean is important.
