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