Safely eat some acidic things (lemons, for example, contain citricĪcid) but not others (drinking a chemical like sulfuric acid would beĪcids and alkalis are simply chemicals that dissolve in water toįorm ions ( atoms with too many or too few electrons). What's even more confusing is that we can We know it's a substance thatĬan "burn" our skin (though it's a chemical burn, not a heatīurn), but that's about it. What it is before you start! Most of us have only the faintest idea If you're interested in measuring acidity, it helps if you know Others will burn your skin and can do painful, permanent damage.

It can be hooked up to a computer with a USB cable to download data from its internal memory, which can store 500 measurements. This sophisticated two-probe, digital meter is made by Hach. Photo: US naval hospital technicians test a water sample for acidity, alkalinity, and chlorine levels. What are pH meters and how do they work? Let's take a That's why many people invest in a meter that can measure pHĭirectly. With the litmus risks killing off your prized pets or your plants. Like soil of a certain acidity or alkalinity, getting things wrong Tropical fish, for example, or you're a gardener with specimens that But sometimes that's too crude a measurement. Out how acidic or alkaline something is on what's called the Your little strip of wet paper with the colors on a chart and figure Same rhyme: "and if it turns blue, it's an alkali true." MeasuringĪcids and alkalis (bases) with litmus paper is something pretty muchĮveryone learns how to do in school. If it turns pink, it's acid I think-you probably learned that useful phrase once upon a time, along with the second half of the The pH measurement results can automatically be exported to a spreadsheet, database or LIMS.By Chris Woodford. The intuitive and adaptable pH meter software has the flexibility to allow you to manually select and set up wells containing samples for pH measurement, as well as the ability to import sample data from an Excel spreadsheet, LIMS or database. The Rapid_pH software performs pH probe calibration and allows the user to view the pH probe calibration results. Our benchtop pH meters includes a laptop computer preloaded with the Rapid_pH software, facilitating easy setup in under 30 minutes. Unlike manual pH meters, these laboratory pH meters automatically reads sample pH, rinses (DI water) and air dries the pH probe, then repeats the cycle for remaining samples. These automated pH meter will increase your pH measurement throughput and free up your time to work on other important tasks.
The Rapid_pH family of laboratory pH meters use robotics to automatically measure pH in microplates, tubes and vials, reducing the time and tedium associated with manual pH measurement in the lab.
