Sensorex S651 Electrode

Water quality conductivity, disolved oxygen, and pH/ORP sensors with built in or remote digital & analog microtransmitters

A smart sensor incorporates some of the signal processing and data manipulation capabilities of a transmitter or controller directly into the sensor. Smart sensor electronic modules essentially function as a “micro transmitter,” eliminating the need for additional instrumentation.

Simplify installation

No transmitter required

Sensorex Smart Sensors are a robust, small footprint solution: great for saving space in a panel. These versatile sensors feature open protocol digital (MODBUS) communications or analog (4-20mA), giving you the flexibility to build customised systems without being locked in to one manufacturer’s instrumentation.

Increase confidence in readings

MODBUS enabled smart sensors can store valuable data, like the part number and date of manufacture, making this information more readily available. Output calibration history and impedance values can be output, providing sensor health diagnostics.

Quick configuration

Sensorex Smart Sensors are easy to configure using our free software. They can be pre-calibrated at your facility, eliminating the need to calibrate in the field.


Typical applications

These submersible ORP & pH electrodes are ideal for tanks, flumes and sewer lines.
