Floating smart water monitor for pools and hot tubs. Continuously monitors temperature, pH, ORP (sanitizer level), and total dissolved solids. Part of the Hayward ecosystem. Uses the pHin app to recommend chemical adjustments.
About pHin
pHin is a smart floating water monitor that continuously tracks pH, ORP (sanitizer effectiveness), and water temperature in pools and hot tubs. Founded in 2015 in Cleveland, Ohio by Bryan Rabin and Ryan Prestel, pHin secured $7 million in investor funding and was acquired by Hayward Industries in 2018 for an undisclosed amount. pHin now operates as part of Hayward's connected pool ecosystem alongside OmniLogic automation and AquaRite salt systems.
The pHin monitor connects via Bluetooth to a WiFi bridge (or directly to the Hayward OmniHub), and the pHin app provides continuous monitoring with weekly chemical dosing plans. pHin's unique chemical delivery service ships pre-measured chemical packets directly to pool owners based on their actual monitor readings — taking the guesswork out of pool chemistry entirely.
