The Precipitator Demonstrator PR-1, also known as a TDS indicator, is an effective sales tool and acts as a visual demonstration which displays the differences between a customer's tap water and filtered, purified water. The PR-1 model requires 2 Iron Rods (IR-1) and 2 Aluminum Rods (AR-1). Don't let the demo fail because you don't have replacement parts! Replace rods from an aesthetic perspective as appearance does not effect performance.
