State-of-the-Art Solution
An efficient and easy to use solution for simplistic leak testing that provides reliability and accuracy with every result.
Product Overview
Designed to provide clear and non-subjective results, the Uson 628 is a differential pressure decay leak tester that rivals the performance of more complex and expensive instruments. By offering five different pressure ranges, ranging from vacuum up to an impressive 15 bar, it covers a wide range of applications, from medical check valves to automotive radiators and beyond. With its highly sensitive and budget-friendly design, this tester is your ultimate ally in reducing product deviations and recall issues through the early identification of leaks.
But that’s not all – the Uson 628 is packed with features that truly set it apart from the competition. With the ability to create and save up to 30 test programs, you can easily recall your preferred settings for fast and efficient testing. The electronic regulator option goes even further, allowing you to test at multiple pressures with the pre-fill option as standard.
The 628 tester is capable of running multiple tests, including differential pressure and vacuum decay, ensuring comprehensive and accurate results every time. Equipped with a 24-bit high resolution for precise measurements, as well as industry-proven proprietary sensors and valves, this tester provides reliable operation that you can trust.
