The PHEH digital pH, ORP and temperature sensor has been designed to perform under the harshest of conditions from pure mountains water with conductivity as low as 20 μS/cm, lakes and rivers (100 – 2000 μS/cm), seawater with conductivities of 50 mS/cm to wastewater with conductivity higher than 200 mS/cm. The PHEH sensor features a “long life” reference. The Plastogel® PONSEL technology. This increases the lifetime of the probe, along with the need to refill. The probe has been designed to operate with the Odeon handheld, as well as in situ applications which have typically been the most difficult situations for a pH/ORP sensor in terms of the sensors resistance, response time, minimal flow dependence and low power consumption.
Digital Technology
The Smart PHEH sensor stores all calibration history within the sensor. This allows the sensor to be interchanged between different systems without losing accuracy.
Thanks to the sensors Universal Modbus RS 485 and SDI-12 communications the sensor can easily be connected directly to system incorporating this communication such as PLC, SCADA systems, telemetry and data logging systems
