Leaks for System Integration

Manufacturers of helium leak testing systems require
calibrated leaks of various sizes with individually adjusted
leak rates for the purpose of setting up and calibrating their systems.
Depending on the type of application, these calibrated
leaks are either installed in the test sample as a master leak or are installed in the test chamber itself.
INFICON offers calibrated leaks which are capable of meeting the requirements
concerning type and required leak rate.

These types of calibrated leaks are only available on request. Please send us your request to get a feedback about feasibility and to get all important information for the order.
