How to Test Salt Water Pools

Saltwater pools are favorites as they do not require harsh chemicals to help keep the water disinfected; they simply use salt. When using a salt water pool, you must keep the salt level at a minimum of around 3500 parts per million with salinity refractometer or other tools,  according to our suggestions. To ensure that a salt water pool stays at the appropriate salt level, it is important to test the water. Most salt water pools have their own salt level readout; however, these readouts can sometimes fail, and thus it is important to have one or two backup methods available.

Experiment Ideas for Science Projects Dealing With Foods

Experiment ideas for science projects dealing with foods can cover numerous avenues of inquiry, ranging from why certain baking ingredients combine better than others to why foods spoil. The average kitchen can serve as a laboratory for chemistry and biology experiments. You can test a simple process with a brix refractometer or sugar refractometer or other tools , such as the growth of sugar crystals, or a more complex process, such as the ripening of fruit.

Water Salinity Testing

Water salinity testing is used to determine the concentration of salts dissolved in a water sample. Salinity is measured for maintenance of saltwater aquariums, to determine the suitability of water for drinking and for ecological monitoring of aquatic habitats. Salt concentration can be directly measured by evaporating a water sample and measuring the dried salts left behind (total dissolved solids, or TDS). More practical methods such as salinity refractometer Method for estimating water salinity have been developed based on the relationships between the concentration of salt ions and electrical conductivity, density and refractive index.

How to Reduce Moisture Content in Honey

Bee keepers are in the habit of keeping a watch on their hives and testing the honey that is extracted for moisture. Anything above 18 percent is considered excessive. It could result in the honey fermenting and spoiling. Honey that is ready to be extracted will need to have the moisture removed. You can do this with brix refractometer or bee refractometer in a few ways.

How to Use an Atago Refractometer

A handheld digital refractometer measures the refractive index of a solution, based on how light bends, or refracts, when traveling through the solution. This allows the user to determine the concentration of sugars, salts, proteins or minerals in a sample. One of the most common applications for a refractometer is checking sugar levels in drinks at beverage plants and breweries. The Atago refractometer can measure hot and cold samples on its prism surface. The percentage displayed on its digital readout shows the total concentration of soluble solids in the sample.

How to Monitor the Brix of Fermenting Wine Must

Brix is a measurement of the amount of sugar in a liquid. The sugar converts to alcohol during fermentation. As Brix numbers decrease, the amount of alcohol in the liquid increases. Measure Brix with a device called a hydrometer.

How to Mix Saltwater for an Aquarium

Saltwater aquariums require regular water changes with synthetic salt mix. Otherwise toxic chemicals and compounds can build up in the water and impact the health of your fish and plants. You also need to check the salinity of the water with the salinity refractometer before it is added to the tank. It's important to mix the water properly and thoroughly, and to use purified water. You can obtain purified water at a reduced price at your local fish store.

What Tools Could Be Used to Measure Salinity?

Salinity is the measure of how much salt is present in a sample of water. This measurement is important for many scientific purposes, but in everyday life, salinity is most commonly measured to determine the quality of drinking water and in saltwater aquariums. There are two main tools that are used to measure salinity -- hydrometers and refractometers -- and both are simple to use.

How to Measure the Salinity of a Freshwater Aquarium

The water in freshwater aquariums has almost no salt content. At times, it becomes necessary to add salt to kill bacteria or because of problems with parasites that cause aquarium fish to lose their scales -- the added salt helps the fish maintain salt in their blood during the healing process. However, as a general rule, salt should never be added to a freshwater aquarium. Freshwater aquariums with a higher than normal salt content should be adjusted through a 30 percent water change -- as opposed to the weekly 15 percent water change -- as soon as possible. A salinity refractometer can tell you exactly how much salt is present in your freshwater tank.

Seventh Grade Science Fair Projects About Bananas Ripening

Bananas primarily grow in the hot and humid tropical regions that lie near the Earth's equator. They are typically cut from the plant while still dark green and start to ripen immediately. The starch inside the banana changes into sugar during ripening, making the banana sweeter and creamier. You can use banana ripening experiments to introduce your seventh graders to scientific equipment and challenge their growing academic ability.
