What is dip test means?

A dip test is a method used to determine the concentration of a substance, typically in liquids, by immersing a test strip or device into the sample. The resulting color change or reading is then compared to a standard scale to quantify the concentration. This technique is often employed in various fields, including environmental monitoring, medical diagnostics, and food safety testing. Dip tests are valued for their simplicity and speed, providing quick results without the need for complex laboratory equipment.
