Presto offers an amazing range of pH meters. It is an ideal and precise instrument used to calculate the pH of an extensive range of solutions and chemicals. The laboratory instrument is preferably used in Paint & Plating industry for material testing. The very reliable and Table top model introduced by Presto strictly complies with various international standards like ASTM and JIS etc. The testing instrument is incorporated with an ATC (Automatic Temperature Compensation) to measure accurate pH readings under different weather conditions and various temperature settings. Also, the testing equipment is designed with a Gel filled pH Electrode, which provide highly accurate and reliable results.
How does Presto’s pH Meter work?
To operate the machine, dip two electrodes in the solution. This helps the hydrogen ions move to outside towards the surface of the glass electrode and change some metal ions in it, but some of the metal ions move from glass electrode to the chemical or solution. This method of exchange is known as ion exchange. It shows that how a glass electrode works. This working procedure shows different degrees of hydrogen ion activity on the surface of glass at different places which means a different percentage of electrical charge produces on different surfaces. This difference shows the pH measurements on the meter. The testing equipment ensures highly reliable, reproducible and accurate results. It is used for all types of solutions, chemical, paints, dyes and many more.
