Portable pH Meters
Portable pH Meters
Instruments used to measure the acidity or alkalinity of a sample, and designed for portability and durability.
Portable pH meters are most often used away from the physical lab to measure the acidity or alkalinity of liquids in more remote locations.
A pH meter actually measures hydrogen-ion activity in water-based solutions. The liquid’s acidity or alkalinity is expressed as a pH unit. The pH scale ranges from 0 to 14, meaning a liquid with a pH below 7 is acidic and a pH above 7 is basic. A pH of 7 is considered neutral.
Also called electrochemistry meters, pH meters are potentiometric and determine the difference in electrical potential between the measuring electrode and a reference electrode.
Some portable pH meters accomplish routine tasks, often used to determine the pH of swimming pools and meet other commercial needs. These are sometimes called pH testers. Indicators or litmus papers can also be used to qualitatively measure pH.
Modern portable pH meters are typically digital and may detect more than pH. Some are equipped to measure specific ions, dissolved oxygen content, or conductivity.
Many portable pH meters are waterproof to protect against accidental dropping or adverse environmental conditions like rain or snow. Some electrodes are also equipped with longer cables to allow for submersion in a reservoir of water or other liquid.

Cole-Parmer Oakton EcoTestr™ pH 2+ Pocket pH Meter
Additional key provides an easier, more intuitive interface. Improved cap functions as a sample cup and as a stabilizing base to stand the meter upright. IP67-rated housing is waterproof and floats. This new addition to the Oakton EcoTestr product line features updates to make measuring water quality easier and faster. The display is larger with a better viewing angle, has indicators for battery life, readiness, and calibration, and shows both the parameter and temperature readings at the same time. To enhance field use, the cap was redesigned to be leakproof and can be attached to the top of the meter when not being usedno more lost caps! The cap features a fill line, so you know how much sample you need for an accurate reading when using the cap as a sample cup. It is also wider, providing a base to keep the meter upright for hands-free measurements. The keypad now has a fourth key to simplify menu navigation while keeping convenient one-touch calibration.
