pHin Tests Water Chemistry Differently

pHin Tests Water Chemistry Differently

Traditionally, water chemistry is measured about one time per week. This certainly helps to monitor the health of your water, but we, at pHin, have developed a smarter approach. pHin measures your vessels’ pH, sanitizer and temperature over 1000 times per week.

There are many environmental factors that affect water chemistry like: usage, weather, water temperature, sunlight exposure, etc. pHin’s built-in intelligence takes all of that collected information, analyzes it and then creates recommendations based on your pool or hot tub’s unique averages.

This means that pHin’s recommendations may be different from what you are used to or what your pool store recommends, but we find when customers follow our recommendations their pools are more likely to stay balanced.

We're all About Delivering Peace of Mind

We work tirelessly to ensure you have peace of mind knowing that your pool is “in the blue”. We guide you with scheduled actions to maintain a healthy pool or hot tub as well as recommended actions that are customized to your water’s unique chemistry.

Customers who have followed the guidance in the pHin app, report that their water has never looked clearer, nor has it been easier to maintain.
