S406 DIFF/N

Differential digital pH and ORP sensors for waste water treatment plants and aggressive industrial applications Reference electrode with salt bridge and KCL reserve Built-in temperature sensor IP68 rated protection.

MAIN FEATURES
• Reliable ORP measure thanks to the use of a process of digital measurement
• Communication of measurements via MODBUS RTU protocol
• Differential method of measurement enables a longer electrode life in time and in the most prohibitive applications
• Possibility to execute all the calibrations via MODBUS RTU serial port
• Black RYTON® sensor body
• Absence of moving mechanical parts
• Immediate installation and easy maintenance

These sensors are fully interchangeable with any ORP electrode and are suitable for use with any MODBUS RTU ORP meter. They are able to communicate the values of the measure ORP and Temperature via MODBUS RTU protocol, and you can perform all calibrations through the serial port.

APPLICATIONS
ORP electrodes S406 DIFF/N are designed for measurements of ORP in heavy duty applications where ORP electrodes standards would not be able to work because the life of reference would be too short.

The S406 DIFF/N ORP sensor is constituted by a RYTON® body which houses the glass electrode for measuring the ORP, the reference electrode with a salt bridge, the temperature sensor, the earth contact of the solution and the electronic board of signal handling.

As already said, the S406 DIFF/N uses the proven technique of differential measurement in three electrodes, the ORP and the reference electrode are compared to a ground electrode for a rate measuring accuracy, even in chemical applications difficult. The bridge replaced and the tank can be refilled ensure a long service life in
applications containing sulphide (H2S) and metals such as lead, mercury, and silver.

The electrode will maintain a constant potential in the reference cell dilution resisting the variations of pressure and temperature over time. Not surprisingly, examples of applications where differential ORP electrodes are the most suitable choice are: wastewater treatment plants, suspended solids fouling processes, processes with pollutants, processes with high concentrations of sulfides, coagulation and flocculation, scrubbers, galvanic processes, surface finishing, processes of elimination or recovery of heavy metals.
