Digital Aerosol Photometer independent filter certifiers

The APM-18 is designed on the base of light scattering principle, displays real-time leakage rate by detecting aerosol concentrations of upstream and downstream. it has solid die-cast aluminum housing, easy for maintenance and calibration having a measuring scope of 0.0001% to 100.0% and has alarm for user selection and visualisation. It also has vibratory alarms to notify the user when the defined set point is exceeded. Light source of the aerosol photometer is for Long time. It can work under low power and generate low heat and deviation value

• 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.
