Three Tips for Sensor Care
Whether measuring pH, opacity, brix, turbidity, or Oxidation-Reduction Potential (ORP), sensors serve as the front line of data for many key business decisions. Without good data from sensors, you can’t trust your systems performance and your decisions may not be as informed as possible. Sensor maintenance and care, therefore, should be an important part of your operational procedures. In addition to helping with systems performance and business decisions, keeping sensors maintained can also save money in sensor replacement costs, and if there is a chemical feed dependent on sensor input, the chemical feed will be more effective. Remember these three tips for proper sensor care and maintenance:
- When cleaning, do not use any other chemicals or methods than those recommended in the operating manual.
- Inspect sensors frequently to determine if cleaning needs to occur more or less than the operation manual suggests, as your conditions may not be similar to typical installations.
- When cleaning pH or ORP sensors, blot rather than wipe after the final rinse as a wiping action can introduce a static electrical charge to the glass that can interfere with the initial reading.
