Introduction :
The PHEH sensor has been designed to perform under hard 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 and to wastewater with conductivity higher than 200 mS/cm.
This sensor features a “long life” reference. The Plastogel® PONSEL technology increase the lifetime of the probe the need to refill.
This sensor has been designed also for handheld and in situ applications which have been the most difficult situations for a pH/ORP sensor in term of sensor resistance, quick time response, minimal flow dependence and low power consumption.
Digital Technology
The “smart” pH/Redox/Temp sensor stores calibration and history data within the sensor. This allows you a “plug and play” system without re-calibration.
Thanks to the Universal Modbus RS485 protocol, the PONSEL pH/Redox/T sensor can be connected to all devices commonly used (Datalogger, Controller, Automat, Remote System…).
