Varify TDS Water Meter

Varify is a health-focused brand originally founded in San Diego, California, with the mission of making water quality testing accessible and understandable for homeowners and families. The brand specializes in both chemical reagent test kits and digital monitoring devices, such as the 4-in-1 TDS meter which measures Total Dissolved Solids, Electrical Conductivity, and water temperature.

While the brand is headquartered and its products are designed in the United States, manufacturing is primarily carried out by specialized partners in China. This model allows the company to offer lab-validated, high-precision tools at an affordable price point for residential use. Varify remains an independent American company that maintains strict quality checks and partners with non-profits like 'Water For Good' to support clean water initiatives globally.
