Commonly Used Instruments For Leak Detection Of High Efficiency Filters
Dust particle counter
It is used to measure the size and number of dust particles in a unit volume of air in a clean environment, and can directly detect clean environments with cleanliness levels ranging from ten to three hundred thousand. Small size, light weight, high detection accuracy, simple and clear functional operation, microprocessor control, can store and print measurement results, and test clean environment is very convenient.
5C Aerosol Generator
The TDA-5C aerosol generator can produce consistent aerosol particles of various diameter distributions, and the TDA-5C aerosol generator can provide sufficient challenge particles when used with aerosol photometers such as TDA-2G or TDA-2H. Measure high-efficiency filtration systems.
detect
Domestic high efficiency air filter testing is mainly based on GB/T 13554-2008 "High Efficiency Air Filter", GB/T 14295-2008 "Air Filter", JB/T 6417-1992 "Air Filter for Air Conditioning", GB/T 6165-2008 "High Efficiency Air Filter Performance Test Method Filtration Efficiency and Resistance", the detection methods include sodium flame method, oil mist method and counting method, and the sodium flame method is the benchmark method. It can be seen from the evolution of the international high-efficiency filter testing standards that the testing methods of high-efficiency air filters mainly include sodium flame method, oil mist method, DOP method, fluorescence method and particle counting method.
