EN 1822-4 High efficiency air filter (EPA, HEPA and ULPA) Part 4: Determining leakage of filter elements (scan method).

Upgraded Pro system with more powerful functions

SC-13011 Small Filter Tester is used to test the filter efficiency and resistance of small filters. It's technical specifications comply with the relevant product standard EN 1822-5 high efficiency air filter (EPA, HEPA, ULPA) filter element efficiency measurement.

It is used for the performance test of Class F filters. It can test the resistance, ePM1.0, ePM2.5, ePM10.0, and the flow resistance curve of various types of filters, including flat, W-type, bag and cylindrical filters.

This equipment is used to test exhalation and inhalation resistance of masks. According to the different standards, the models are divided into SC-RT-1703GB, SC-RT-1703KR and SC-RT-1703EN.

The SC-RT-N1704 Respirator Valve Air Tightness Tester is used to test the leakage air flow of the exhalation valve of the mask.

Product profile
Test indexes: filter efficiency and resistance of melt-blown, medical face mask, non-powered air-purifying particle respirator N/P 95/99, FFP 1/2/3, filter element etc.
Particulate matter in the ambient air was used as the test medium. The test is a non-standard test condition, but the final result corresponds to the test result under the standard test condition through calibration.
