Since 2003, WaterLeakTest.com— a brand of KOVAZ s.r.o.—has been at the forefront of water ingress detection in the automotive industry. What began as a modest engineering initiative with ŠKODA Auto in our home country, the Czech Republic, has evolved into a comprehensive portfolio of testing solutions trusted by manufacturers across Europe, Asia and the Americas. Our early ambition was simple: to make water-leak testing faster, safer and more dependable for technicians on the production line. Two decades later, this ambition continues to guide everything we do.
From our patented wick-sensor technology to the robust WLTe 200 handheld tester and its modular adapter ecosystem, our products are designed to address the real conditions of modern vehicle manufacturing. Whether used in laboratory environments, for pre-series validation, or in 24/7 series production, our tools help engineers identify water ingress long before it becomes a costly quality issue.
Today, WaterLeakTest.com solutions are deployed in more than 25 OEM plants and operate within 12 countries, supporting both passenger-car and commercial-vehicle manufacturers. Our close collaboration with engineering teams, combined with an emphasis on durability, accuracy and ease of use, has made us a trusted partner for leak-testing applications across a wide range of platforms—including the increasingly complex requirements of electric vehicles.
We understand the daily challenges faced by quality and production teams. That is why we remain committed not only to developing reliable technology, but also to providing guidance and tailored support—helping manufacturers achieve consistent, verifiable water-tightness results with confidence.
