Phenol Red – Determining the pH Measurement

Phenol Red is commonly used for measuring pH levels in water. When dissolved in a water sample, the tablet produces distinct color changes, indicating the pH value. Monitoring pH is crucial for ensuring the effectiveness of disinfectants in water treatment and preventing issues like corrosion or precipitation, which can damage materials. Lovibond® tablets are formulated with thiosulphate to neutralize the interference of chlorine in pool water testing. It’s important to also consider factors such as carbonate levels, water temperature, and buffer capacity, as they can impact the accuracy of pH measurements. This tablet is specifically designed for use with photometers.
