Product Description

IntellipH ™ pH Controller


The automatic dispenser that keeps your pool's pH in perfect balance Regulating pH levels is vital to an enjoyable, smooth-running pool. Left unmanaged, improper pH can lead to clouded water, irritated eyes and damaging calcium scale buildup. The IntellipH system dispenses a constant dose of muriatic acid to keep your pool's pH in check. And it makes adjusting pH levels as easy as touching a button. Together with the IntelliChlor salt chlorine generator, it helps balance and sanitize your water for a clear, sparkling pool.



  • Protects your pool equipment from corrosion when pH swings out of balance
  • Dispenses pH-lowering acid at a rate you can adjust with the touch of a button
  • Maximizes the sanitizing power of chlorine by eliminating fluctuations in the pool water's pH levels
  • Pump style lid seals securely assuring safe operation
  • Bolts securely to the equipment pad to prevent poolside acid spills
  • Large 4 gallon reservoir results in significantly less manual handling of muriatic acid
  • UL and cUL listed

Can the Pentair IntellipH automated acid dispenser be used standalone or does it have to be used with the Pentair Intellichlor salt chlorine generator.

A  Answered on 4/3/2012 by InyoPools Product Specialist Patrick P.

The Pentair IntellipH automated acid dispenser is designed to only work with the Pentair Intellichlor salt chlorine generator. These two systems together can be incorporated with the Pentair Easy Touch or Intelli Touch automated systems
