Measurements to determine acidity are performed in many educational institutions in courses such as chemistry, environmental science, pharmacy, food science, physics, etc. 

Conventional glass based pH electrodes are fragile and require special attention in terms of use and maintenance. As a result glass pH electrodes tend to have short lifetimes in many educational institutions. 

Sentron produces robust glass free pH probes that can handle the wear and tear of a typical classroom laboratory and can be stored under dry conditions. Hence Sentron’s pH probes and meters are ideally suited for educational use.
