What Cincinnati Test Systems does

Cincinnati Test Systems (CTS) is a U.S.-based designer and manufacturer of leak detection equipment and leak test systems, headquartered in Harrison, Ohio, and operating since 1981. The company offers a comprehensive portfolio built around multiple testing methodologies, including pressure decay, vacuum decay, mass flow, and tracer gas (helium/nitrogen) detection, anchored by the Sentinel family of programmable test instruments, the TracerMate II tracer gas instrument, the CTS Connect line of pneumatic and manual sealing connectors, and the CTSnet software platform for data management and instrument control. Integrated turnkey test systems, calibrated NIST-traceable leak standards, IP67 testing systems, helium recovery systems, and function/hydrostatic/burst test systems round out the offering. CTS also operates an A2LA-accredited ISO/IEC 17025 calibration laboratory, providing manufacturing and recertification of calibrated leak and flow standards.

CTS operates as a business unit within TASI Test and Automation's Product Integrity segment, alongside sister brands innomatec, Sciemetric, and Sierra CP Engineering, benefiting from the parent conglomerate's global test, inspection, automation, and assembly infrastructure. The company serves manufacturers across at least eleven verticals, including automotive, eMobility/battery, medical devices, HVAC and refrigeration, consumer electronics, military and defense, energy, appliances, data center cooling, transportation, and die casting. Its go-to-market relies on direct enterprise field sales supported by application engineers and a network of local representatives, with multilingual support extending into China and Korea; consumables and connector accessories are additionally sold through the CTS Connect online storefront. Revenue is generated primarily through hardware sales of instruments and systems, supplemented by professional services (calibration, training, on-site lab trials) and recurring consumables and seal parts.

The 2017 acquisition of German custom test systems specialist H. Schreiner Test- und Sonderanlagen extended CTS's European footprint and custom engineering capacity. The company maintains continuous product extension into growth verticals, notably EV battery pack and cooling system testing, data center cooling leak verification, and IP67 waterproof electronics testing, alongside operationalization of its calibration lab for NIST-traceable standards.

Core offering

Cincinnati Test Systems designs and manufactures standard and custom leak test systems and leak detection equipment for industrial manufacturers. Its portfolio spans multiple testing methodologies - pressure decay, differential pressure decay, vacuum decay, mass flow, and tracer gas (helium and nitrogen) - delivered through the Sentinel line of test instruments, TracerMate II tracer gas instruments, CTS Connect sealing connectors, CTSnet data management software, ISO 17025 calibrated leak standards, and fully integrated custom-engineered test systems.

Product overview

Cincinnati Test Systems (CTS) offers a comprehensive portfolio of precision leak detection equipment and flow testing solutions, spanning multiple testing methodologies including pressure decay, differential pressure, mass flow, vacuum decay, and tracer gas (helium) detection. The core product line centers on the Sentinel family of leak test instruments (IX5, Blackbelt Pro, Blackbelt, I28, LPC 528, C28WE, C20WE, MH, 3520) and the TracerMate II for tracer gas applications. These instruments are deployed within complete test systems—ranging from benchtop pressure decay and mass flow units to sophisticated hard vacuum helium systems with helium recovery. CTS complements its instrumentation with a full ecosystem of accessories including CTSnet software for data management, ISO 17025-calibrated leak standards, and the CTS Connect line of pneumatic/manual connectors and seals for reliable part fixturing. The company also delivers turnkey integrated test systems combining instruments with custom fixturing and automation, supported by calibration services, on-site lab trials, and operator training. Founded in 1981 and headquartered in Harrison, Ohio, CTS operates as part of TASI Test and Automation's Product Integrity segment alongside innomatec, Sciemetric, and Sierra CP Engineering.
