What should I look for if I need to purchase a pH meter
If you are required to check any liquid pH with a meter, you need to consider the accuracy. Accuracy is listed as a range of +0.XX pH units. This means that the meter may read so many pH units above or below the actual pH of the product. Purchase a pH meter with an accuracy of +0.02 units or better. For instance, a pH meter with an accuracy of +0.01 is a good choice, better than that of +0.05 or +0.1.
