Definition - What does Test Strip mean?
A test strip is a material used to measure the concentration of a chemical or some characteristic of a liquid. Test strips are most often used to test a liquid's pH level, but some types of test strips serve other purposes, such as detecting the presence of a contaminant.
A test strip is usually a piece of a paper that contains an indicator. This indicator will change to a different color depending upon the pH level of the liquid to which it is exposed. The test strip's new color is then compared with a pH color scale to determine the acidity or alkalinity of the liquid.
Corrosionpedia explains Test Strip
A test strip is a very cost effective way to determine the pH level of a liquid. A package containing many test strips can be purchased at a very economical price due to the fact that they are simply pieces of paper.
The information a test strip can provide regarding a liquid's pH is invaluable to corrosion prevention. Knowing the acidity or alkalinity of the environment can help prevent or mitigate corrosive reactions before they are able to cause a failure.
The pH scale typically used with a test strip consists of the numbers 1 to 14, with 1 being the most acidic and 14 being the most basic.
