Cincinnati Test Systems

Throwing it back to 1991.

This turnkey dual-chamber helium leak test system for condenser testing was installed over 30 years ago… and it’s still in operation today.

Built with a desktop PC featuring 4MB of RAM, a DOS 3.3 operating system, floppy drives, tape backups, and technology that looks very different than what we build today. While technology evolves, one thing hasn’t changed: manufacturers still need reliable, repeatable leak testing solutions that stand the test of time.

Not every machine built in 1991 is still running production today. We think that says something.

Let’s build your leak testing solution together.

Congratulations to everyone who participated in our CTS Weight Loss Challenge. No matter what your journey looked like, showing up and committing to yourself, and encouraging others (through some healthy competition), for 90 days is something to be proud of.

Congratulations to our top finishers based on percentage of weight lost:

🥇 Josh Wanner - 28.52% lost (77.6 pounds)
🥈 Brandon Roberts - 25.14% lost (57 pounds)
🥉 Kelly Roberts 18.16% lost (43.8 pounds)

Together, our 23 participants lost an incredible 364.6 pounds!

To celebrate everyone who participated, we wrapped up the challenge with a Chipotle lunch — because this wasn’t just about the final numbers. Although, our top finishers did get to split the prize pot — funded by participant buy-ins and matched by CTS!

Whether participants hit their goals, built new habits, stayed motivated, or simply gave it their best effort, we wanted to recognize everyone’s commitment over the past three months. Great job to everyone who participated and supported each other along the way!
