Plug-in device turns iphone into pH meter


Apps and add-on devices for smartphones are increasing allowing users to conduct testing in the field. Cole-Parmer’s pH module with pH electrode converts the iPhone, iPad and iPod into a pH meter. ORP and pH measurements can be taken using any electrode with a BNC connector. The display shows pH measurement, mV reading, ambient temperature and ATC temperature. The module provides automatic and manual temperature compensation shown in degrees Celsius or Fahrenheit. Data can be transferred by e-mail or through a USB connection. The pH meter calibration may include up to 99 points. Cole-Parmer Canada Inc.
