pHin is Easy to Use and Set Up

pHin is a smart water monitor with an app that measures your pool, hot tub or spa’s temperature, sanitizer and pH levels over 1000x each week, analyzes the data and creates recommendations based on the water’s quality.

pHin also prompts you to dip a monthly test strip when it’s time to determine your water’s cyanuric acid, total hardness and total alkalinity levels and quickly provides a detailed water report with actionable information.

*Monitoring Subscription is $99/year after the first year, and includes a 1 year product replacement extension with each renewal

pHin is the leading smart water monitor for pools, hot tubs or swim spas.
