The Aquistar TempHion Multi-Parameter Water Quality Sensor with integrated power and datalogger, is capable of measuring pH, specific ions (chloride, bromide, nitrate), redox and temperature. Each unit comes with one thermistor based temperature element, as well as up to four pH, ISE or redox elements.

The TempHion is internally powered by two AA batteries or with an external power supply for data intensive applications.

The TempHion can be programmed via laptop or desktop using the RS485/RS232 adaptor and easy to use Aqua4Plus software. Once it has been programmed, the sensor measures and collects data at a range of time intervals.

Through the Aqua4Plus software, the internal processor allows for easy calibration. After calibration completion, the data is stored in a non-volatile memory in the smart sensor. This information is then applied to previous recorded data, resulting in highly accurate readings at a wide range of temperatures.
