About Tecna Marposs

Tecna is an Italian manufacturer of leak and flow testing instruments and a Marposs Group company. It was founded in 1983 in Mirandola, in the heart of northern Italy’s biomedical manufacturing district, and joined Marposs in 2016. Its instruments are sold today as Tecna Marposs and Marposs Tecna within the Marposs leak test family, with US sales and support through Marposs Corp. in Auburn Hills, Michigan.

What Tecna makes

Tecna built its reputation on compact, precise air testers for plastic medical parts, tubing sets and bags. It then applied the same measurement electronics to die-cast housings, hydraulic components, appliance circuits and electric-vehicle assemblies.

The product line centers on the Provaset family. T3L bench and fixture instruments cover absolute pressure decay, differential pressure decay, flow testing and direct leak-rate measurement, and the T3LMF mass flow version handles large internal volumes such as battery packs and cooling plates. The compact Provaset T2 fits cleanroom benches, while the rugged 2SEAL is aimed at heavy mechanical production. For automation, TM3 modules bring the same measurements to assembly machines and rotary tables with up to sixteen channels.

Verification tools, solvent dispensers for medical bonding and data-collection software round out the offering. As part of Marposs, Tecna’s air-based instruments sit alongside helium tracer gas systems and turnkey leak test machines from the wider group.

Why engineers specify Tecna Marposs

The right method for the part. Absolute, differential, flow and mass flow techniques share a consistent interface style, so plants can match the method to each component while keeping a familiar operator experience.
Scales from bench to line. The same measurement family runs from a single T2 bench station to a sixteen-channel TM3 automation cell.
Verification built in. The LTC simulates known leaks in line and works with other brands’ testers, supporting consistent gauge checks.
Connected data. Depending on model, instruments offer Profinet, Modbus, Ethernet, USB, RS232/RS485 and barcode traceability, and store up to 300 test programs.
Quality and backing. Tecna operates under ISO 9001, with Marposs’s global organization behind it.

Local support from Vaughn Associates

Vaughn Associates represents Tecna Marposs across all of its Southeast territories. The region’s automotive corridor, including vehicle assembly, powertrain and EV battery production, and its medical device, HVAC and appliance manufacturers all rely on fast, repeatable leak and flow checks.

Our sales engineers help you define the leak specification, part volume, test pressure and cycle time, then choose between pressure decay, differential, flow or mass flow methods and between bench instruments and automation modules. We coordinate quotes and application questions with Marposs and follow up after installation. Instruments are typically purchased directly from Marposs.

Product lines

What Tecna makes — product categories we can help you specify.

Stand-alone leak and flow testers (Provaset T3L series)

Full-featured bench and fixture instruments with color touch interfaces, each built around a specific measurement principle and able to control external automation and traceability devices.

Provaset T3LP absolute pressure decay
Provaset T3LD differential pressure decay
Provaset T3LPF flow and leak
Provaset T3LPQ direct leak-flow

Mass flow leak testers for large volumes

Instruments that measure make-up flow directly instead of pressure change, keeping tests sensitive and fast on large parts such as EV battery packs, cooling channels and tanks. The T3LMF works from vacuum to 6 bar.

Provaset T3LMF

Compact leak testers

Small-footprint pressure decay testers for manual benches and cleanrooms or for rugged shop-floor use, with PLC control available.

Provaset T2
2SEAL

Multi-channel leak test modules (TM3 series)

Headless measurement modules built into assembly machines, rotary tables and multi-station cells, with up to sixteen independent channels run from one operator interface.

TM3P absolute pressure decay
TM3PF flow and leak
TM3PQ direct leak-flow

Flow testing

Flow-rate checks that confirm correct passage through orifices, channels, filters, nozzles and medical tubing, either alongside or instead of a leak test.

Provaset T3LPF
Provaset T3LPQ
TM3PF
TM3PQ

Calibration and verification devices

Reference tools for routine gauge checks, pressure calibration and leak simulation, so operators can confirm testers are measuring correctly.

LTC Leak Tester Control
Leak Master

Medical assembly accessories

Supporting equipment for medical device lines where leak testing sits next to manual solvent bonding.

FAQ

Common questions about Tecna

Is Tecna part of Marposs?

Yes. TECNA S.r.l., founded in 1983 in Mirandola, Italy, became part of the Marposs Group in October 2016, and Marposs announced the acquisition that November. Some US trade coverage did not appear until 2018, which is why that year is sometimes cited. Tecna instruments are now marketed as Tecna Marposs or Marposs Tecna, with US sales and support through Marposs Corp. in Auburn Hills, Michigan.

When should I choose mass flow leak testing over pressure decay?

Pressure decay works well on small and medium internal volumes, but on large parts the pressure change caused by a small leak becomes tiny and slow to resolve. Mass flow testing measures the make-up flow directly, so it stays sensitive and fast on big volumes. Marposs positions the Provaset T3LMF for EV battery packs, cooling channels and tanks, with a stated resolution of 0.01 cm³/min.

What is the difference between Provaset T3L testers and TM3 leak test modules?

Provaset T3L instruments are stand-alone testers with a color touch interface for benches or test fixtures, offered in absolute pressure decay, differential, flow, flow-sensor and mass flow versions. TM3 modules have no display of their own and are built into automated machines and rotary tables. They run one to sixteen channels from a single operator interface, and different module types and ranges can be combined.

How can I verify that a leak tester is measuring correctly on the production line?

Tecna offers two verification tools. The Leak Master is a calibrated reference leak and pressure calibrator for periodic checks. The LTC (Leak Tester Control) installs in line between a leak tester and the part, simulates known leaks and confirms the instrument responds correctly. Marposs says the LTC also works with testers from other manufacturers, so plants can standardize one verification routine across mixed equipment.

Does Tecna Marposs offer helium leak testing for EV batteries?

Tecna's own instruments use air-based methods: absolute and differential pressure decay, flow and mass flow. Helium tracer gas testing, including vacuum chamber tests for battery cells, accumulation chambers for packs and trays, and sniffing systems, comes from the wider Marposs leak test business, which grew with its 2006 acquisition of French helium specialist Trace. Engineers can therefore source air and tracer gas stations from one supplier group.

Who represents Marposs Tecna leak testers in the Southeast?

Vaughn Associates, an independent manufacturer's representative headquartered in Huntsville, Alabama, represents Tecna Marposs across all of its territories: Alabama, Georgia, South Carolina, Tennessee, Arkansas, Mississippi, Louisiana, Florida, North Carolina, Virginia, Maryland and Washington, D.C. Vaughn's sales engineers help select test methods and instruments for each part and coordinate quotes and application testing questions with Marposs.
