Description
Technical field
The utility model relates to detecting instrument apparatus field, particularly a kind of for on-the-spot high-efficiency filtration systems integralityThe aerosol photometer detecting.
Background technology
The filter efficiency of high efficiency particulate air filter itself is generally detected by manufacturer, while dispatching from the factory, reports with filter filter efficiencyList and verification of conformity. Concerning pharmacy corporation, high efficiency particulate air filter leak detection refers to the scene after high efficiency particulate air filter and system thereof are installedLeak detection is mainly little pin hole and other damages checking in filter filtration material, as frame seal, washer sealing and filter structureCrack on frame etc. The object of leak detection is by checking high efficiency particulate air filter and the sealing of locating with installation frame connecting portion etc. thereofProperty, find in time high efficiency particulate air filter itself and install in the defect that exists, take corresponding remedial measure, ensure the cleaning in regionDegree. The leak hunting method of high efficiency particulate air filter is mainly divided into aerosol photometer method of testing and batch particle-counting system method of testing. Use at presentAerosol photometer be U.S. ATI2I type photometer, range of dynamic measurement is 0.00005～120ug/L, sampling flow is1F3/min (28.3L/min). Its scope of application is narrower, has limited technical staff's use. Therefore, how to provide a kind of high propertyThe aerosol photometer of energy becomes the major issue that checkout equipment field need to solve.
