Industry Solutions
Zaxis leak testers support configurable air leak testing across medical, automotive, electronics, consumer-goods and industrial manufacturing.
Zaxis serves a wide variety of industries with fast, affordable and reliable leak testing solutions.
The modular design of Zaxis leak testers allows product engineers to configure a tester around an application and production process.
The same modular components are used throughout the Zaxis family of leak testers, from a large desktop 7i used by an R&D department to compact automation testers such as the iKit.
That shared platform supports straightforward test validation through the product-development process. Zaxis created a true multi-tester for applications that need more than one test.

Zaxis Isaac HD and 7i testers can run multiple programs and test types in a single machine for applications that require more than one test.
An administrative IV set can require both a pressure-decay test and a flow test. The Zaxis Isaac HD and 7i can run multiple programs and test types in one machine for that kind of validation.
Medical devices used in procedures can require strict FDA and ASTM standards, while packaging lines may test one package on a bench or thousands of fill-form-seal packages.
Methods used
Match the test medium, part behavior, allowable leak rate and production workflow before selecting a leak-test approach.
Pressure decay pressurizes a sealed product, isolates that pressure, and measures loss during a defined interval. It is used on IV sets, tubing, catheters, bags, sensors and other closed products where a repeatable pass/fail limit is needed.
Set pressure, volume and the permitted decay for the product’s intended use.
Pressure decay explained →Vacuum decay evacuates a sealed part and watches for a loss of vacuum. It can serve flexible medical bags, enclosed assemblies and EV battery components where a non-destructive air test is useful.
Use a stable fixture so the measured change comes from the part rather than its connection.
Vacuum decay explained →Mass-flow testing measures the gas moving through a component and compares it with an expected flow rate. It supports open-path parts such as catheters, tubing and automotive components that need both flow and leak information.
A flow limit can distinguish a blocked path from one that passes the required air. The fixture and target pressure must match the component.
Mass-flow testing explained →Chamber testing places a product in a controlled chamber for exterior seal evaluation when no direct port is available.
The chamber approach lets packaging and sealed-product teams use a pneumatic test while keeping the product dry.
Chamber testing explained →These Zaxis platforms address varied industry production workflows. The Isaac HD, iKit and 7i referenced on this page were discontinued on 03/31/25 with limited parts after 2028; their successors are the Z5, Z1 and Z8.
Z5Compact multi-channel tester for factory automation: up to four independent channels in a 6.5" × 7" × 9" footprint.
Z8Up to four test ports, sequential or concurrent, with an 8-inch touchscreen and 2–1,000 PSIG range.
Z1Single-channel tester built for machine integration; cascade units for synchronous multi-channel cells.Zaxis can configure leak testing for single bench applications or large-volume production lines.
Modular tester designs support product development and production workflows.
Pressure decay begins by applying pressure to a closed product, isolating it, and measuring the pressure loss over a defined time. It is widely used for IV sets, tubing, catheters, bags, implantable devices and sensors because it can detect small non-water leak rates while remaining fast for production.
Vacuum decay uses the inverse condition: the part is evacuated and the test monitors vacuum loss. Mass flow instead measures gas flow through the component, which makes it useful where the product has an intentional open path. Chamber testing evaluates a sealed product from outside the part when a direct connection is impractical.
The right method follows the product’s form, function and environment. Determine whether the goal is to keep a material in, keep particulates or liquid out, verify an open passage, or protect a sealed cavity. Then establish the pressure condition, fixture and allowable result for that product.
A leak-test specification must be strict enough to protect product performance and practical enough to avoid rejecting good parts. A limit that is too tight can add material and time costs; a limit that is too loose can allow field failures, recalls and lost confidence.
Repeatability starts with a stable setup. The part, fixture, air supply and test conditions need to support the same measurement cycle from one unit to the next. Sensitivity, resolution, test time and the product’s real operating conditions all affect the final selection.
Production planning also matters. A test station must fit the line, communicate the result where needed, and give operators a consistent sequence. Early application work can connect the required leak limit with the right test type and automation approach.
Clean, dry air protects precision valves and sensitive transducers from contaminants and metal particulates. Unfiltered facility air can damage test equipment and interfere with reliable measurements, so air preparation belongs in the test plan.
Part stability is equally important. Temperature, humidity, HVAC activity, open bay doors and shifts in the surrounding environment can change test conditions. A part tested in the morning may behave differently later if the setup does not control those changes.
A well-designed fixture, sensible limits and routine calibration help separate an actual product leak from variation in the test setup. Build the process around the part and review the causes of inconsistent results before increasing the test limit.
The PCB and components in a desktop 7i used by an R&D department are the same as those in the compact iKit automation tester, so a test validated on the bench carries into the line.
An IV administration set that needs both a pressure-decay test and a flow test can run both programs in a single Isaac HD or 7i.
From one package on a lab bench to thousands of fill-form-seal packages, testers are configured for automated operation to increase output and reduce user error.

A 7i used in R&D and a compact iKit automation tester use the same modular platform, helping teams carry test validation through product development.
Yes. An administrative IV set may require both tests, and the Isaac HD and 7i can run multiple programs and test types in one machine.
Medical-device applications can require FDA and ASTM standards; packaging fixtures can be configured for bench or fill-form-seal production work.
Automated leak-test operations can increase manufacturing output while reducing opportunities for user error.

The automotive industry page covers fuel systems, manifolds, powertrain components, electrical parts, EV batteries and airbags.
Select a method around the product’s intended function, whether it is sealed or open-path, its environment, the required leak limit, and the production workflow.
Contaminated air, changing temperature or humidity, unstable parts, poor fixture sealing and an unsuitable test method can all change a result.
Pneumatic testing supplies a measured result without submerging the part, avoiding the drying, contamination and subjective bubble observation associated with dunk testing.
