How to Choose the Right pH Electrode for Your Application?
Modified on: Tue, Aug 30, 2022 at 6:30 AM
Regular pH electrodes like 201T-F, 201T-S, or the glass bulb probes in most Apera pocket testers are only suitable for testing general water solutions — medium to high ion concentration, non-protein solution, non-strong acid, non-strong alkali, at moderate temperature — of which common applications are in hydroponics, horticulture, pools and spas, aquaculture, aquarium, environmental monitoring, water treatment, cooling towers, education, etc.
For testing pH of special samples such as strong acidic, strong alkaline solutions, solutions at high or low temperature (>50˚C or <10˚C), viscous, solid samples, turbid solutions, or low ion-concentration solutions, etc…specialized pH electrodes are necessary in order to achieve reliable results. Regular pH electrodes in these special applications usually would not generate reliable measurements and could be damaged by certain types of samples, or even be non-applicable for testing at all.
