Your Leak Test.
Light Years Ahead.
CTS introduces the Sentinel IX5 – a NEW multifunctional leak tester for pressure, flow, and vacuum leak testing! Featuring an all-new platform – rebuilt from the ground up – with a BOLD new design, new touchscreen interface, and a streamlined user experience.

Leak Detection Instruments for Quality Manufacturing
No matter how meticulously designed or precision-engineered, even the best products can experience manufacturing defects that can cause leaks outside of allowable specifications. Whether it’s gas or liquid leaking from a part or water or dust making it into an assembly, leak testing is a manufacturer’s front line defense to meet performance expectations.

Accurate, Affordable Leak Testing for Every Application
Not every application is complex. There are times when a simple leak tester is the best fit. For basic applications, Cincinnati Test Systems has several simple, low-cost leak testing options that can accommodate single-test options. Despite their simplicity, these leak testers offer quick cycle time, superior performance and accuracy, and easy maintenance.
Simplify the Test Process With Multi-functional Instrumentation
Cincinnati Test Systems streamlines multiple tests into a single, high-performing, multi-channel leak tester that can handle up to four individual tests in a single unit. Performing different test methods with a single multifunctional instrument reduces expenses, speeds the test process, and saves valuable laboratory space. This simplifies the test process and reduces set up costs.
Cincinnati Test Systems offers several benchtop leak test options for mass flow, pressure decay, function tests, pressure testing, and more. Our team of engineering experts stands ready to help you determine which option is best for your specific application. Our leak testers are technologically advanced, high-performing, and extremely accurate.
Standard & Custom Leak Detection Systems
CTS is a world leader in providing reliable leak detection solutions as standard instruments, custom products, and engineered test systems for your specific application. Our leak test instruments feature advanced designs, features and test algorithms to provide reliable and repeatable results for customers in all industries.
Pressure Decay Leak Testing Systems
Detect leaks by pressurizing the test vessel, then cutting the air source to isolate the pressure inside the vessel, and using the leak test instrument controls to measure loss of pressure over a set period of time.
Tracer Gas (Helium) Leak Test Systems
Systems include sniff leak testing, nitrogen pure leak testing, accumulation tracer gas systems, and hard vacuum helium leak tests.
Mass Flow Leak Test Systems
Measure the volumetric flow of air passing through a product to determine the integrity of parts and components.
Vacuum Decay Leak Test Systems
Vacuum decay leak testing is very similar to pressure decay testing, however the part is evacuated instead of pressurized.
