|When it comes to accurate chemical concentration control of wash water, inductive probes are technologically more advanced than conventional conductive probes. Inductive probes read chemical concentration levels by casting a magnetic field from two charged coils that are encapsulated in PVC. These magnetic coils never come in direct contact with corrosive chemicals and hard water minerals. As a result inductive probes provide consistently accurate and reliable chemical concentration control without ever needing to be serviced; unlike conductive probes that need constant maintenance and probe replacement. With inductive probes, even chemical suppliers with cost-guarantee accounts get peace of mind.
