Temperature, pH, ORP and ISE (Ions Selective) meters are used in a laboratory and field (benchtop and portable). They are indicated to control the pH quality in water, milk, wastewater, foods and watery solutions in general.
pH meters uses the potentiometric method for the pH determination or potential hydrogen that indicates the acidity, neutrality and alkalinity of an specific application. It is also used for ion selective concentration measurements for example fluoride, chloride, iodide, ammonia and more.
