Test Adapter / Vacuum Adapter
GPS testing technology offers a large selection of vacuum adapters. The support with vacuum (negative pressure) results in increased ease of use and larger pressures can be built up easily and thus more test needles can be contacted.
We recommend the use of vacuum hoods or, if contact is required on both sides, our vacuum swivel hood.
