Cambridge Sulfur Hexafluoride tester

Cambridge Sulfur Hexafluoride tester

The EN 14175; Part 3 test uses a 10% sulfur hexafluoride – nitrogen mixture with a total delivery rate of 2 LPM for interior plane test (using a 9-point diffuser sampling array); a rate of 4.5 LPM for the exterior plane and robustness test, and a [(5 to 8) / 1,000,000]) fraction of the hood exhaust rate flow for the air exchange efficiency test.
