WaterGuruSense 10” Square Skimmer Adapter - Smart Pool Monitor - Chlorine & pH Meter - Pool Water Tester - Monitor Pool Chemicals

I have had pools for 40 years and hand tested the water each day. This device does it for you each day at the same time. You get the results by push notification and can review them in their app. It measures FC, ph, water temp and flow rate. If FC or ph are out balance it will give you solutions on what to do to correct the balance. It also plots the information it gathers giving you a complete picture of our you pool has been. I still test once.a week with a comprehensive test kit to monitor the overall condition of the pool. The Waterguru has been on target with its readings. I only wish I would have discovered it sooner.

I have taken care of pools for 40 years and this makes life so much easier.

Junk, I’m sending it backIt doesn’t look like the picture, no grid lines, the guru doesn’t fit snugly in itIt doesn’t fit securely in the skimmer. I can’t even put the skimmer top over it because it causes it to sit up too high

Performs as promised. Good support. Well worth the money.

This fits my skimmer cover size but the way it’s built underneath makes it not sit flush. So it wobbles, but kept it since there are no alternatives for the tester.

The skimmer adapter in the picture has grid lines. The one received is flat plastic and the guru doesn’t lock into it. It actually sits on top and has a gap. Then the adapter doesn’t sit in the skimmer box and sits on top with a gap. Makes the guru worthless.
