Are you having trouble with leak test after washing process? We can help you reduce measurement errors and false rejects caused by the influence of work temperature.
When the work temperature is higher than the ambient temperature in such a case as after washing process, the temperature change of the work as a result of thermal exchange with the clamp fixture affects the leak measurement. To cope with it, the measured value can be compensated using the correlation between the differential pressure change and work temperature that causes measurement errors. The Temperature Compensation realizes highly accurate leak tests and reduces false rejects.
