PH-1 Turns iPhone, iPod, or iPad into Portable pH Meter

Sensorex (USA) has developed an industry-first mobile accessory for pH measurements. Compatible with Apple iPod, iPhone and iPad devices, the PH-1 pH meter accessory measures and records pH values in the lab or field for use in environmental, education and industrial applications.

The patent-pending PH-1 accessory plugs into the standard Apple dock connector and uses a Sensorex pH electrode to measure pH with accuracy to .01 pH. The free Sensorex app displays pH, millivolts, ambient temperature and solution temperature in real time. The CE marked device supports 1, 2, 3, or more calibration points and sends readings by email for later analysis. When used with a GPS-enabled device, the pH meter app will record measurements with both timestamp and geographic coordinates, eliminating transcription errors and improving efficiency.

Powered from the Apple device, the PH-1 requires no supplemental energy source. Its pH measurement range is 0-14 pH and it operates in ambient temperatures of 0-40° C, in solutions of 0-100° C. Data history can be grouped by date or location and exported individually or in .csv format via email.
