The ODM PH-1 accessory combined with its pH Meter companion app brings pH measurement to the iPhone and iPod touch. The accessory plugs into the iPhone and has a reader attached for taking the pH and temperature readings. The companion app records the readings, as well as the location, time, and date of the readings.
The could be a fabulous little kit for scientist working in the field for environmental testing, or even for commercial pool maintenance. Another great use would be in the science labs of schools - the labs could have a handful of the accessories and students could take turns using their iPhones and iPod touch's to take readings for their projects.
