Accessory Turns iPad Into Portable pH Meter
Sensorex has developed a 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 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 degrees Celsius, in solutions of 0-100 degrees Celsius. Data history can be grouped by date or location and exported individually or in .csv format via email.
