pH test strips are widely used in various fields to measure the acidity or alkalinity of a solution. In laboratories, they are employed for quick and simple pH testing during experiments and quality control processes. In the food and beverage industry, these strips ensure products meet safety and quality standards by monitoring pH levels. They are also essential in agriculture for testing soil pH, helping farmers optimize crop growth by determining the need for soil amendments. In aquariums and pools, pH test strips maintain water quality, ensuring a safe environment for aquatic life and swimmers. Additionally, they are used in healthcare for diagnostic purposes, such as testing urine or saliva pH. Their ease of use and portability make them a convenient tool for on-the-spot pH measurements in diverse settings.
