pH Measurement

Term from Laboratory Work industry explained for recruiters

pH Measurement is a fundamental laboratory skill that involves determining how acidic or basic a substance is. It's like using a thermometer for temperature, but instead measuring the acidity level of liquids. This skill is essential in many industries including food production, water treatment, medical labs, and chemical manufacturing. Scientists and lab technicians use special tools called pH meters or pH strips to get these measurements. When you see this on a resume, it shows the person knows how to accurately test and record acid/base levels, which is crucial for quality control and safety in laboratory settings.
