Meet the Sensorex SAM-1: a smart device that turns your smartphone into a pH, ORP or conductivity meter. Just have to plug the device into the audio jack of your smartphone, and plug in the smart sensor, and you are set. You can use this device to measure samples in the lab, field, or plant. Users have the option to download readings as .csv files. The device is compatible with iOS devices, but an Android version is in the works.
