DESCRIPTION
The AquiStar TempHionTM Smart Sensor is a submersible pH/temperature sensor and datalogger combined in one small diameter unit.

The TempHion Smart Sensor records over 65,000 records of pH, temperature, and time, operates on low power, and features easy-to-use software with powerful features.

Several TempHions, or a combination of TempHions and PT2X Pressure/Temperature Smart Sensors, can be networked together and controlled from one location, either directly from a single computer or via a WaveData Wireless Data Collection System.

OPERATION
The TempHion is powered internally with two AA batteries or with an auxiliary power supply for data intensive applications. INW offers alkaline, rechargeable, and other auxiliary power systems.

The internal processor in the TempHion Smart Sensor allows for easy calibration, using the calibration utilities in INW's Aqua4Plus software.Once calibrated, this calibration data is stored in non-volatile memory within the Smart Sensor. When data is collected, this calibration information, along with sensor specific temperature and pH calibration information, is applied to the data, resulting in highly accurate readings at a wide range of temperatures.

APPLICATIONS
The TempHion can be used for pH monitoring in a wide variety of applications. Its patented reference electrode provides long-term stability for continuous or intermittent monitoring making unattended insitu pH testing possible, without frequent calibrations or service.
