Our accumulation machine utilises mass spectrometry technology, helium or hydrogen tracer gas, and airflow generators to accurately measure the total leak rate of a product down to 1.0 x 10-3 mbar*L/sec. This is done without the need for a vacuum pumping system or leak-tight chamber, as tests are conducted at atmosphere. The lack of a pumping system and vacuum chambers reduces the price of the machine when compared to traditional Hard Vacuum machines.
Changes in temperature and volume do not affect machine performance and repeatability. As a result, products can be tested straight after processes involving heat, which can contribute towards overall productivity.
