CALIBRATION OF SECONDARY STANDARD LEAKS BY MEANS OF MASS COMPARISON

Dominik Pražak, Jaroslav Zůda, Ladislav Peksa

Abstract

Gas leak detection is getting more important in the last years. Primary standards for leaks can be divided into sensitive and insensitive to gas species. The method proposed by authors is insensitive to gas species. The basic principle of the method is mass comparison and detection of the difference between standard weight and the leak to be calibrated. The authors made several measurements to prove the repeatibility of the method. It can be seen that to get results with reasonable uncertainty the weekend measurement is sufficient.
