Differential PH/ORP Sensor - S401DIFF / S406DIFF

The sensor S401 Diff is used for differential measurement of pH in pure water, 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.

Applications
• pH Measurement

Features and benefits
• Reliable pH 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 serial port
• Black PVC sensor body
• Absence of moving mechanical parts
• Immediate installation and easy maintenance

pH electrodes S401 are designed for measurements of pH in heavy duty applications where pH electrodes standards would not be able to work because the life of reference would be too short. The S401 pH sensor is constituted by a PVC body which houses the glass electrode for measuring the PH, the reference electrode with a salt bridge, the temperature sensor, the earth contact of the solution and the electronic board of signal handling. These sensors are fully interchangeable with any pH electrode and are suitable for use with any pH meter. They are able to communicate the values of the measure pH and Temperature via MODBUS RTI protocol, and you can perform all calibrations through the serial port.
