...The realities behind calibrating a Vernier Drop Counter—tips on how to save time between uses. Bonus—get a free centering widget for your Drop Counter.
...In education, a common application for an ORP sensor is a potentiometric titration. Similar to an acid-base titration, a titrant is added to a sample incrementally until all the sample has reacted and the end-point is reached. Students can apply...
Keep your pH sensor hydrated, clean your pH sensor, and maintain your pH calibration solutions to ensure your pH sensors always give you great data. Plus, a bonus tip to save money on buffer solutions.
...A calibration equation is stored on each pH Sensor before it is shipped. For the most accurate measurements with this sensor, we recommend you perform your own 2-point calibration with buffer solutions.
As the pH Sensor ages, the performance of the...
pH is a quantitative unit of measure that describes the degree of acidity or alkalinity of a substance. It is measured on a scale of 0 to 14. The formal definition of pH is the negative logarithm of the hydrogen...
