Detailed reviews of the best pH meters

When reading the reviews remember that distilled water has a pH of 7, and that the pH scale goes from 0 to 14. In addition take note that pH meters are different from ORP meters, TDS meters and dissolved oxygen sensors, although they are often used in combination to rate the quality of different type of liquids.

The Etekcity High Accuracy Pocket Size Handheld pH Meter is an easy and affordable way to accurately test the acidity or alkalinity of solutions. Simply immerse the electrode in a solution thats either alkaline or acidic and read the pH value right of the device. This product is ideal for everyday testing and hobby use, but even though the accuracy is said to be between 0.01 and 0.05 pH, don’t expect extreme ph scale accuracy without at least calibrating the device with a buffer solution.

Etekcity High Accuracy Pocket Size Handheld pH Meter is perfect for simply testing the pH of the water in swimming pools, aquariums or in the tap. It can also be used in a basic laboratory setting, but since it is not very durable and the accuracy can be questioned, we recommend one of the other more professional pH meters featured in this article for laboratory use.

This pH meter by Etekcity is the best selling product in the Lab pH Meters category on Amazon.com, and with an average user rating of 3.9 from over 560 reviewers, you can be certain that this is an excellent choice if you are looking for a low end, affordable and all around pH meter as an acid/alkalinity indicator.
