Despite the growing recognition of the importance of the pH directly surrounding a cell as an indicator of cell health, techniques to measure it so far remain limited

These new meters are available in two versions—the ST400, specifically designed for pH analysis and the ST400M—a multi-parameter meter ideal for both pH and conductivity testing

A new generation of DIY scientists are building some very complex instruments

Introducing the world’s first stir bars capable of continuous pH measurement and spin monitoring along with temperature feedback

The pH tester PCE-228P has been designed for use in cosmetics like skin creams and lotions, shampoos and conditioners

Updated testers are ideal for all professionals in the lab or out in the field who need to test water quality

Some sample measurements can pose unique challenges that require special pH measurement considerations

When scientists must measure more than one parameter, a multimeter might be the right tool.
