A pH meter is a type of laboratory equipment that is used to measure the acidity or alkalinity of a solution. It is an essential tool for many laboratory and industrial processes, including food and beverage production, water treatment, and pharmaceutical manufacturing. The pH meter measures the hydrogen ion concentration in a solution, which is expressed as a pH value. The pH meter is used to measure the pH of a solution, which is a measure of the acidity or alkalinity of the solution.
The pH meter is available in a variety of models and price ranges, ranging from basic handheld models to more advanced, computer-controlled systems. The price of a pH meter depends on the features and accuracy of the model. Basic handheld models can cost as little as $50, while more advanced models can cost up to $1,000 or more.
