What to Look for When Picking the Best pH Meter for Wine Making

pH Meter Design

Your choice of the best pH meter for wine can be found in a variety of styles such as pen, handheld, benchtop etc. So far pen-style pH meters tend to be the most portable since they can be easily packed into travel cases or your pocket.

Handheld pH meters may require 2 hands for operation but this doesn’t necessarily mean that they aren’t portable. These devices may be a little larger than pen-style pH meters because they offer greater functionality and are typically also shockproof and waterproof.

Finally, benchtop pH meters are mostly intended for indoor use hence it shouldn’t come as a surprise that they aren’t very portable. However, these devices make up for this drawback by offering more dedicated functions and multiple electrodes.

Accuracy, Range, Resolution

The higher the accuracy offered by a pH meter, the more return on your investment you can expect. However, this particular consideration may ignore the fact that more accuracy also commonly means a higher price. The average pH meter may have an accuracy of +/-0.01 to +/-0.2 but the best pH meters for wine making may also offer up to +/-0.001 accuracies.

On the other hand, range refers to the pH range of the device and most meters can measure up to 0 to +14. There are, however, also some models that are programmed to measure extended pH levels from -2 to +20. Lastly, resolution signifies how much information can be displayed by a pH meter. For instance, a 0.1 resolution implies that it displays pH in tens.

Temperature Correction

If this is your first time using a pH meter, you should also know that temperature can have a significant impact on pH readings. Temperature correction can, therefore, counter this effect but is usually only present in sophisticated meters.


Calibration on pH meters can either be done automatically or manually and the former is usually done with a simple push of a button. On the other hand, manual calibration is done with the help of adjustable knobs but usually has a longer learning curve to get used to.


The electrodes of pH meters often require periodic replacement since the solution inside them may eventually dry out. To avoid this from happening, you can use sealed electrodes but these can only be used for one reading. Refillable electrodes are the way to go if you wish to save some money in the long run, but they will cost more up front.

Our Final Thoughts

When it comes to the best pH meters for wine making, the biggest deciding factor tends to be the sensitivity and accuracy of the device. That being said, all 5 of our handpicked pH meters offer the most sensitive calibration and accurate results in the market.
