An electrochemical pH paper sensor
Currently there are two common ways to measure pH, a pH meter or pH paper:
pH meter: Must be used with care and is difficult to maintain, specifically, they must be calibrated and cleaned before each use. Also, large volumes of liquid must be tested.
pH paper: This method is subjective and semi-quantitative, it lacks the ability to give an exact measurement of a solution, and is only accurate for a quick check of whether a solution is acidic, basic, or neutral.
The hand-held electrochemical reader and screen-printed electrodes can be used as a disposable device or can also be reused several times. The paper test strip for liquid samples is a one-time-use, which serves for sample delivery and storage. This electrochemical pH paper sensor can also be combined with other electrochemical detection technologies for simultaneous multiplex detections such as glucose, heavy metals, etc.
