pHmeters

XS AND pH: ITALIAN EXCELLENCE! The pH, by definition, is the negative logarithm of the concentration of H + ions in a solution; in mathematical terms: pH = -log [H+]. Values range are from 0 to 7 for acidity and from 7 to 14 for basicity. The pH measurement is important in all sectors of the food, pharmaceutical, cosmetic, galvanic industries, etc. pHmeters are digital instruments that are used to measure the pH value of a product or an aqueous solution. The pH measurement chain consists of: - An indicator with digital display - A pH sensor (electrode) - One electrode connection cable Since the electrode response is influenced by the temperature variation, to correct this variation the instruments are often also equipped with a temperature sensor that detects the temperature of the product / aqueous solution to compensate for the electrode response. pHmeters can be portable and benchtop. They usually have similar characteristics. The main difference lies in the size and type of power supply. The portable ones are small in size, battery operated and easy to carry around. Benchtop ones have larger displays and are suitable for working on a laboratory bench and often come with an electrode holder arm. Almost all pHmeters have the possibility of connecting a Redox sensor as well, to read the redox potential (Rx) expressed in mV.
