Filter Photometer Integrity / Leak Testing Of HEPA Filtration
Systems
Aerosol photometer is used for on-site leakage detection after the
installation of the efficient filter and its system, mainly to
check small pinholes and other damage in the filter, such as frame
sealing, gasket seal, and leakage on the filter frame. The purpose
of leakage detection is to check the sealing of the efficient
filter and the connection part with the installation frame, timely
find the defects in the installation, and take corresponding
remedial measures to ensure the cleanliness of the area.
The APM-18 can automatically switch the upstream and downstream
aerosol concentration to determine the filter for leakage. The
portable scanning probe enables the operator to quickly and
accurately identify the leakage points in remote locations and
determine other leakage ratios, and when the alarm line is
exceeded, the display board displays an alarm.
Features and Benefits of aerosol photometer
- long life laser light source;
- high precision photoelectric multiplier tube detection;
- can set PAO, DOP and other types of aerosols;
- equipped with a dedicated handheld device to achieve control,
display and sampling function;
- large capacity data storage, real-time data storage;
- more than the setting alarm sound and light alarm;
- can be obtained by U disk or thermal printer to print historical
data;
- can print leakage rate and other monitoring data in real time;
- through the special software, the sampling data can be imported
into PC;
- automatic fault detection.
