We are more than willing to support you with your request or run a demo with your packaging.

Designed to verify precise seal force in vacuum chambers and on Speedpack

The Audion Seal Pressure Measurement device (ASPM) verifies the seal force of seal bars not being driven by a loadcell (such as vacuum chambers and Speedpack).

For Audionvac*:

Seal pressure of a validatable vacuum chamber equals the differential pressure between the vacuum chamber and the seal bar activation pressure, this value can be measured by the ASPM. The seal pressure readout of the Audionvac can easily be compared with the ASPM.


*in order to guarantee precise air pressure all validatable Audionvac should be connected to external air of 1,2 bar

For the purpose of validation processes it is crucial to regularly check the seal pressure of a validatable vacuum chamber or validatable Speedpack. It is highly recommendable to order the Calibration service together with this device.

The ASPM comes standard in a solid plastic case, which protects the device during transport and storage.

Seal pressure verification set for validatable vacuum chambers and Speedpacks:

  • Conforms to the industry requirements
  • The test result is clearly presented on the digital screen
  • Packed in a solid case

Calibration, Verification and Validation Services

The Audion validatable packaging machines require calibration, verification and validation services on a regular basis. Audion offers a wide range of instruments and solutions enabling users to test and verify their packaging machines and seal integrity, in order to meet the high market requirements.

  • Available verification instruments include:
  • ATM (Audion Temperature Meter): to verify the seal temperature
  • AFMR (Audion Force Measurement Ring): to verify the seal force of a validatable industrial sealer and to adjust the sealer in accordance with the measured values (Power Sealer and MSIDV)
  • ASPM (Audion Seal Pressure Measurement): to verify the seal pressure realized by compressed air (vacuum chambers and Speedpack) and to adjust the machine in accordance with the measured values
  • AVLM (Audion Vacuum Level Measurement): to verify the vacuum pressure
  • Seal Integrity Test (SIT) as a service which includes: 



  • Seal check according to ISO 11607-2 (to check intact seal for a specified seal width)
  • Dye penetration test according to ASTM F1929 (to check no channels or open seals)
  • Peel test according to EN 868-5 Annex D (to check tensile strength of seal)
  • Audion Factory Calibration (incl. Calibration Certificate): (Re-) calibration executed by certified engineers certifies the preciseness of the critical sealing parameters of the packaging machine. Reference standards calibrated under ISO17025 accreditation
  • IQ/OQ Check:
    • Installation Qualification (IQ): an Audion service engineer inspects the packaging machine in your operating environment, checking the following aspects: correct installation, functionality, specifications, critical process parameters and documents. Includes training & certificate.
    • Operational Qualification (OQ): an Audion engineer tests and will register seal integrity of your bag(s) in a test plan. Includes determination of sealing parameters, tolerances, acceptable criteria and worst case testing.
