Articles about pH Meter

Learn about the pH meter principle and application of this useful chemistry tool. From medicine to agriculture, pH can be used to understand chemicals and perform safety checks.

Given pH can vary between city water treatments, growers must be able to properly read their local water’s pH so that they can start their healthy indoor gardens. While deciding on the best pH meter is the first concern, growers and scientists must consider knowing how to store pH meter [...]

pH is an integral aspect to many scientific disciplines, where most scientists will likely consider pH at some point in their research or industry. For instance, did you know corals cannot properly grow their calcium skeletons when pH is too low? Ocean acidification directly threatens coral species, affecting all life [...]

pH is a reference to how “acidic” or “alkaline” an aqueous (or water-soluble) solution is. SLP Sørensen is credited with creating the first pH scale back in 1909 as a way to denote this difference. This eventually evolved into the 0-14 pH scale scientists use today. Liquids with more hydrogen [...]

pH is a measurable parameter with implications in biology, chemistry, agriculture, and food science. In fact, pH initiates the color change in hydrangeas, where lower pH (around 5.2) allows aluminum intake, making the flowers appear blue. An increase in pH (around 6.0) prevents aluminum intake, thus turning the flowers pink.pH [...]

Studying Microbe Colonies Are you curious about what pH probes measure, why pH is important, and how  devices that measure pH work? In high school chemistry, you might have used pH litmus paper strips to test liquids, but pH measurement probes can be far more accurate than paper test strips. [...]

pH is critical to life. In fact, for lifeforms living in liquids, such as the ocean, the pH of that liquid dictates what species can survive there. For example, scientists are concerned for ocean life, because rising CO2 levels from climate change actually decreases the pH of the ocean, making [...]

If you remember those science experiments from school where you used litmus paper to test solutions, you probably know what pH is. In essence, it's a common scale used to measure the acidity and basicity of a solution containing water as a solvent (aqueous). Without the presence of water, you [...]

The goal of any pH reading, whether with a manual or an automated pH meter, should always be to obtain high quality pH meter readings. Surprisingly many laboratory scientists and technicians are not aware of how to ensure they always obtain high quality pH meter readings. While some tests and [...]

The pH measurement of a solution is most often done using electrical probes, which detect the difference between the electrical potential of a standardized probe calibrated in standards that bracket the range of pH to be measured, and the samples. The difference between the electrical potential can be converted to [...]
