APM 550 EL Specification
Size Selective inlets | PM 10 Impactor and WINS Impactor for PM 2.5 conform to USEPA design |
Flow Rate | 1 m3/hr maintained by microprocessor based electronic controller Auto shut-off of sampler if flow rate drops by more than 10% from designed value of 16.7 LPM |
Vacuum Pump | Oil Free, non-pulsating pump driven by induction motor for stable flow rate |
Power requirement | Nominal 220 V, Single Phase, 50Hz AC mains supply. For proper operation and safety a good earth connection is mandatory |
Automatic Sampling | In-built system to control start and stop times of sampler |
Volumetric flow rate compensation | Performed automatically by the system using Sensors for Ambient Temp., Barometric Pressure and Filter Pressure |
Elapsed time indicator | Real Time clock based. Operating time for each sample in hours and minutes is recorded |
Flow recorder | USB flash memory based system records flow rate, volume of air sampled, air temperature, filter temperature, filter pressure and barometric pressure |
Volume Totalizer | MCU unit totalizes and displays volume of air sampled |
Display | Large 40 Ch. X 4 line back lit LCD provides all system parameters at a glance |
Software and reporting | PC based software provides intelligent report of all system parameters recorded during. Summary of run time parameters provided at end of sample duration |
Warranty | One year |
