Sensorex has developed a mobile accessory for pH measurements that is compatible with Apple’s iPod, iPhone and iPad devices.
The company’s 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 the pH of a solution. The app displays information including pH, millivolts, ambient temperature and solution temperature.
The device itself is CE marked, can support upwards of three calibration points and sends readings by email for later analysis. The device can also be used alongside a GPS-enabled device, allowing the pH meter app to record measurements with both timestamp and geographic coordinates to aid in the transcription of data.
Powered from the Apple device, the PH-1 requires no supplemental energy source. Its pH measurement range is 0 to 14 pH and it operates in ambient temperatures of 0 to 40 degrees Celsius and in solutions of 0 to 100 degrees Celsius. Data history can be grouped by date or location and exported individually or in .csv format via email.
