Leak testers used in a factory must be robust, safe, accurate and repeatable. Some modern leak testers are also being asked to gather data for statistical analysis and to make decisions based on selected parameters.

A new tester, the H2000, from Sensistor Technologies Inc. (N. Billerica, MA) uses the hydrogen method to fulfill all of these needs. It detects the leak, finds its location and determines the leak rate. The H2000 can be used in automatic and manual testing operations, and can be built so that it will act as a go/no-go station.
