Even when life gets busy the pool is tested.
“I am retired, and didn't think I would need/want something like the WaterGuru. But it sounded interesting so I bought one. I'm so glad I did.Those times when pool maintenance gets away from you, or because your away from home for a few days, you can always check on the fly to make sure everything is where it should be when it comes to your chemicals.”
David A, Arizona

Far better than test strips.
“The first thing most people are going to say is that it’s expensive, and I can buy lots of test strips for that price.Both items are valid, but the big difference is you are getting accurate readings and tracking of data.A test strip only gives you an approximation of where your levels are at.It’s a guessing game as to what the accurate reading is based on color.Guess wrong, and you are either out of balance or wasting chemicals.WaterGuru saves me money.”
Brad B, Michigan

The perfect tool for the job.

* Note, ORP systems do not measure chlorine. They use a rough estimating technique called oxidation-reduction potential that only provides a millivolt reading indirectly related to free chlorine but affected by pH, temperature, cyanuric acid, organics, and other factors. The sensor drifts from contaminant fouling and requires daily calibration.

** ORP Systems typically use glass bulbs to measure pH. They must remain wet and will fail if dried out. Also, they will freeze and will fail if the temperature is at or below freezing.
