About PoolWaterLAB

Ishtvan Kokhan – Founder & Owner of PoolWaterLAB Pool Builder since 1996 • Active PHTA CPO InstructorNSPF Certified Instructor (#04-101495)

PoolWaterLAB was founded by Ishtvan Kokhan, a pool industry professional who has been building pools since 1996 and training pool operators for the past 30 years.

Ishtvan is not a “tech inventor” working in a lab — he’s a working pool professional who has spent decades on real job sites and in real backyards. His experience covers the full scope of the industry: construction, service, water chemistry, and ongoing pool operations. Today, he continues to build and maintain both residential and commercial pools, while also running a service operation that supports customers year-round.

As an active instructor with the Pool & Hot Tub Alliance (PHTA), Ishtvan has trained countless pool professionals on water safety, chemistry fundamentals, and best practices in the field. That same professional mindset shaped PoolWaterLAB — a brand built around one simple idea: If you can’t measure accurately, you can’t manage confidently.

PoolWaterLAB isn’t a consumer gadget — it’s a professional measurement tool designed for objective results, repeatability, and reliability in everyday working conditions. It’s trusted by professionals and also ideal for homeowners who want clear, safe water without guesswork.
