How long should you leave test strips in sanitizer solution for an accurate reading?

The correct duration for leaving test strips in sanitizer solution is typically around 10 seconds. This timeframe allows the chemical indicators on the test strip to accurately react with the sanitizing solution, providing a reliable reading of its concentration.

If the test strips are left in the solution for too short a time, there may not be sufficient reaction to accurately measure the sanitizer level. Conversely, if they are left for too long, it can introduce variables that may distort the result, such as saturation. Therefore, adhering to the 10-second guideline is crucial for obtaining a precise and useful reading, which is important for maintaining health and safety standards in food service environments.
