Description

The closed design of this robust digital differential pH sensor ensures separation of the pH electrode reference system from the medium to be measured, thus excluding electrode poisoning. A dirt-resistant salt bridge with double-junction minimizes cleaning efforts and prevents dilution of electrolytes. The sensor therefore achieves an extremely long service life even in heavily contaminated media. TpH-D is available with a 10 m, 2 m or a 0,5 m fixed cable.

This intelligent sensor stores calibrations internally. This enables a “plug-and-play” system without recalibration when the location or measuring transducer is changed.

Benefits:
• Communication of measurements via digital Modbus RTU protocol
• Differential measurement method enables a longer service life of the electrodes
• Handling of all calibrations via the digital interface
• No mechanically moving parts

Applications:
• Process monitoring and control
• Difficult measurement of inlets to wastewater treatment plants.
