The new Sensorex Model PH-1 meter application accessory for the iPhone or iPod measures pH accurately, presents the data in an easy-to-read format and supports email transmission of critical readings. When connected to the sensor and with the appropriate free app, it provides a real-time display of pH, mV, ambient temperature and solution temperature. The meter accessory features a time/date/location stamp when used with a GPS-enabled device. Results can be grouped by location or date, e-mailed in a “.csv” file format. The accessory is designed for use with the company's Model S200C/BNC combination pH electrode or the Model S293/30K/BNC/2.5 three-in-one pH/reference/temperature electrode. The pH electrode measures over a 0-14 pH range with accuracy to ±0.01 pH. The voltage measurement range is -1250 to 1250mV with accuracy to ±1 mV. The solution temperature range is 0-100◦C with accuracy to ±0.1◦C. Ambient temperature is -40 to 70◦C with accuracy to ±2◦C. Four different pH electrode sensor kit options are available with choices of sensor electrodes, connectors and cables.
