NEW! – Smarter Sensors
Supporting MODBUS/RS485
There is a growing number of applications where conventional water quality sensors and instruments are impractical. With smart water quality sensors, it is possible to monitor water quality in real-time from remote sites or across numerous locations and even while in transit.
Whether your application requires a pH/ORP, Optical Dissolved Oxygen, Conductivity, or a Chlorine sensor, Sensorex has a SMART SENSOR for you.
- Fast response time for accurate monitoring
- Direct 4-20mA analog or MODBUS/RS485 digital output signal
- Easy to integrate with a PLC, SCADA or other control system

NEW! TX3100 Intelligent pH/ORP Controller / Transmitter
Our TX3100 is an intelligent pH and ORP controller/transmitter for reading pH and ORP sensors and programmable process control. This controller replaces the TX3000 1/2 DIN pH/ORP controller and features an updated user interface with user friendly full text and graphical display. This makes operation, calibration, and maintenance easier for operators in treatment plants. The TX3100 also features a solution ground input for accurate readings in applications with ground loop issues.
- NEW graphical display shows sensor data and aids in the calibration process
- 2 programmable relays (Hi/Lo, Hi/Hi, or Lo/Lo)
- Solution ground input eliminates measurement errors caused by reference ground potentials
- Compatible with all Sensorex sensors with tinned leads and PT1000 RTD temp comp
NEW & IMPROVED! CX3100 Intelligent (High Temp) Conductivity Controller
Our CX3100 Conductivity Controller is an excellent choice for high temperature, high pressure applications. Compatible with our CS675, CS676, and CS875 stainless steel conductivity probes, the CX3100 is the only Sensorex controller with automatic temperature compensation up to 200°C. The CX3100 replaces the Sensorex CX3000, and features an updated user interface with user friendly full text and graphical display.
- Monitors conductivity, resistivity, TDS, or salinity
- 1/2 DIN Transmitter/Controller with full text and graphical display
- Ideal for use in high temperature, high pressure applications (with stainless steel conductivity probes)
- Automatic temperature compensation up to 200°C (PT1000 RTD)
