What Are the Different Types of pH Meters?
Measuring pH is important for a range of industries and tasks, helping to maintain safe pH levels for home swimming pools, environmental studies, food production facilities, and more.
By measuring pH levels, it’s possible to determine many factors related to a solution’s chemical conditions. You can identify and act to control nutrient availability, microbial activity, and chemical behavior.
The best way to efficiently and accurately measure pH is by using a high-quality pH meter. So what is a pH meter, and what different types of meters are available?

What is a pH Meter?
A pH meter is an electronic device used to measure hydrogen ion activity, determining the acidity or alkalinity of a product or substance.
The device usually comprises a small measuring probe and an electronic meter, which displays a decimal pH reading.
Measurements produced by a pH meter can be used to show important chemical properties that could impact human health if not properly identified and maintained. Accurate measurements enable workers to take action to avoid the harmful effects of unbalanced pH.
What are the different types of pH Meters?
There are three main types of pH meters, with each option offering different measuring and recording benefits.
Pen tester pH Meters
Pen tester pH meters are pocket-sized and are designed to incorporate the meter, display, and electrode all in one compact instrument.
The small size and diverse capabilities of these meters make them easy to transport from location to location! They’re also often cheaper than larger models.
Pen tester pH meters are often used for construction tasks, as well as for hydroponics, food manufacturing, and pool or spa maintenance measurements.
Handheld pH Meters
Handheld pH meters are larger than pen testers, with the electrode separated from the meter.
These meters often feature interchangeable electrodes, making it possible to fulfill different pH measuring needs. Handheld pH meters are designed to be used on the field. Though a slightly larger option, they remain easy to carry.
Often, handheld pH meters are used for field studies and water treatments or for agricultural and aquacultural tasks.
Benchtop pH Meters
Benchtop pH meters are larger than pen testers and handheld meters. Typically, they are mounted to a desk or wall and are not intended for use on the go.
Separating functions and featuring a larger design, benchtop pH meters are highly accurate, making them the perfect choice for laboratories and professional environments.
Benchtop pH meters are often also used in food-processing facilities and quality assurance laboratories, as well as for water and environmental testing facilities.
Which pH Meter Should you Choose?
When choosing a pH meter, it’s important to consider your measurement needs.
If you work across a variety of locations, easy transport of your meter is likely to be a priority. You may be able to tolerate slightly lower accuracy in favor of a practical, functional device. If this is the case, choose a pen tester meter.
If you often travel for work but can accommodate a larger device and would like to use a slightly more complex pH measuring tool, consider choosing a handheld meter, which will produce accurate results without being difficult to transport.
Suppose you work in a fixed environment where a high degree of accuracy is essential for pH measurements, a benchtop pH meter is your best option, allowing for clear, accurate results when you need them.
