FAQ

Q: Is the TBX5 Series suitable for both pH and ORP measurement?
A: Different versions are available. Please confirm your measurement requirement before selection.

Q: Can this sensor work with non-ABB transmitters?
A: Yes. The analog output is compatible with most standard industrial pH / ORP transmitters.

Q: How often does the sensor require calibration?
A: Calibration frequency depends on process conditions. Regular calibration is recommended.

Q: Can you help confirm sensor suitability before ordering?
A: Yes. Our engineers can review your process conditions and recommend the correct configuration.

The TB(X)5 series pH / redox (insertion, submersion, flow-through and hot-tap sensors) are easily applied to most industrial measurement needs. They are renowned for their ability to outperform conventional sensors in the industries' toughest process applications. Solid-state Next Step™ reference technology is the foundation for all TB(X)5 Series electrodes. The totally solid inner reference chamber is charged with potassium chloride (KCl). This non-liquid reference all but eliminates poisoning, plugging and pumping problems that plague conventional liquid, slurry and gel designs.
