Should You Buy a pH Meter?

A pH meter is an excellent investment if you follow a low-acid or alkaline diet. It's also a good idea if you make your own preserves, as a food's acidity can affect its shelf life.

A pH meter will accurately measure the acidity of any food and drink, and they're easy to use, taking the guesswork out of a low-acid diet.

We have created a handy guide on how to buy the right pH meter.

Types of pH Meters

There are many types of pH meters, but most fit into one of three broad categories: tabletop meters, pen-style meters, and pH test strips.

Tabletop and pen-style meters can be as precise as 0.01 pH but are also more expensive.

Pen-style are the most common for domestic usage, as one person can easily use them.

They're also very accurate, can be inexpensive, and many are waterproof.

  • Are pH Strips Accurate?

Apera pH meter offers a complete test kit.

Some meters need calibration more often than others, and this must be done regularly to maintain accuracy. Meters mainly testing foods with high pH levels may require more frequent calibration than those testing lower pH foods.

Some pH meters have internal storage, allowing you to record the acidity of foods you commonly consume and saving you time.

  • Should I Use a pH Meter for Acid Reflux?

The Best pH Meters

Which pH meter is best depends on your intended use and how much you'd like to spend.

Some pH meters are unsuitable for home use, as they contain substances that would contaminate your food if broken.
