SENSE in action
PATENTED TECHNOLOGY

SENSE’S FILM STRIP

FLOW SENSOR
Measures pool chemistry while your pump is on.

This was my replacement for the Hayward pHin monitor, which was discontinued. Waterguru does everything that pHin did and is more accurate. Major differences: Waterguru has replaceable batteries, disposable sensing cartridges, more intelligence, and you can send in water samples. It uses Bluetooth and WiFi. pHin units used a separate bridge to WiFi, required a monthly test strip sample, and the unit had to be replaced when the sensors or batteries failed.

Our pool looks amazing this year. It's withstood multiple heat waves, thanks to the WaterGuru SENSE pool monitor. Highly recommend. Keeps your pool sparkling clean all season.
Much more convenient than strips and chemical vial. Essentially invisible to the user and swimmers.
