What Do Water Quality Testing Kits Measure?
Choosing the right water quality testing kits can help you get an idea of what contaminants are present in your drinking water. While some contaminants are known to be harmful, others are not. Some contaminants are more common in certain water sources. For example, lead and E. coli can cause serious health issues if they are in high concentrations. You can avoid these issues by testing your water for these and other common contaminants.

Test strips are the most common type of water quality testing kit. These small, single-use strips are easy to use. Each strip is designed to detect a specific contaminant. When the strip is dipped into water, it will change color, indicating the concentration of that chemical. These tests are typically less accurate than other methods, but they can provide a general idea of the concentration of contaminants in the water.
Color disk tests are more accurate than test strips and can provide more detailed information. Color disk kits require a small sample of water, which is placed in a plastic tube. The water sample is then introduced to a powdered “reagent” that changes the color of the water sample. The user then rotates the color disk to find a part of the color disk that matches the sample. The user then reads the concentration of the chemical from the disk. The results are usually more accurate than test strips, but can be subjective.
Digital water meters are also available. These are more expensive than test strips, but they can provide accurate results. These instruments can also measure pH, temperature, and total dissolved solids (TDS). Some digital water meters also monitor the electrical conductivity of the water. The results are usually calibrated to a uS/cm. Most digital instruments are also able to interface with smartphones and tablets, making it easier for users to get the information they need.
Some water quality testing kits also evaluate bacteria. These are usually grouped into two categories: coliform bacteria and E. coli. These tests can be purchased separately or in kits. The coliform variety is the most common type of bacteria. The coliform variety is the most dangerous to humans. It can cause fever, diarrhea, and stomach aches. It is best to contact local authorities or your doctor for more information.
Luminescence testing devices are also available. These instruments provide quick screening of bacteria. The results of a test can be inaccurate if the user is not trained properly. To make sure that you get accurate results, you need to make sure that you wash your hands thoroughly before handling the test. You can also get additional testing at a laboratory.
Home water testing kits are a quick and inexpensive way to test for a wide range of water quality indicators. These kits can detect the presence of bacteria, parasites, and other common contaminants. These tests can also indicate the presence of a variety of different chemicals. The kit will provide instructions, packaging, and test strips, which you will need to complete the testing process.
