Analyzer
Analyzers & Meters
Connect up to 4 sensors to the SF4000 analyzer to display measurements, perform calibrations and diagnostics on a large, 7” touchscreen interface. Sensor parameters are stored directly onboard the SensorFlex electronics to allow sensors to be calibrated in the laboratory. Sensors are provided with connectors that make it quick and easy to install a newly calibrated sensor. For pH/ ORP sensors, where replacement is often more frequent, SensorFlex provides the option to digitize analog sensors. This allows users flexibility with the choice of sensor model for greater operational flexibility.

Sensors & Probes
SensorFlex sensors leverage mechanical and electrochemical design features that have been proven to withstand harsh processes. New digital sensors are also supported with the same design principles that have been applied for decades to ensure durability. In all cases, quick connectors are used at the analyzer and on the sensor near the process to ensure ease of maintenance and calibration.
Digital pH/ ORP
SensorFlex pH/ ORP sensors share the same proven design features as our analog pH/ ORP sensors only with the addition of digital electronics. This provides the ability to store parameters and calibrate in the controlled environment of the lab.

Optical Dissolved Oxygen
SensorFlex supports both ppm and ppb level optical dissolved oxygen (DO) sensors. Optical sensors are quick to respond, consume no oxygen and require little maintenance. Sensors are available with flowcells and insertion mounting provisions.
Toroidal Conductivity
For conductivity measurement in high ionic strength samples, toroidal conductivity sensors have a wide measurement range. Wetted components are entirely plastic thereby improving durability in harsh environments.

Digitizer
Digitizer
The optional SensorFlex™ Digitizer allows analog pH/ ORP sensors to be digitized. Virtually any analog sensor with Variopin VP8 connector and PT1000 temperature compensator can be used. Combining an analog sensor with the Digitizer enables calibration in the lab. In addition, the use of an analog sensor in the process can allow more reliable operation in extreme temperature applications. Formerly A2500500.

What this customer likes about the SensorFlex platform:
- The 5-minute trend on the display which allows him to see spikes in the process.
- Automatic buffer selection for pH during calibration.
- P&ID naming. The tank identification that they use shows up on the screen.
- Ability to enter pH values by typing the numbers directly using the on-screen keyboard. In their previous analyzer they needed to adjust numeric values by repeatedly using the +/- keys.
- The stability indicator on the screen is a god-sent. It takes the guesswork out of it. Previously his operators needed to use their own judgment to determine when a sensor is stable when calibrating.
