Automation GradeAutomatic

We are the proficient manufacturer of APM 550 ELAmbient Air Sampler that is easy to use. Provided with microprocessor based controller, it helps maintaining the constant air sampling rate. Also, the micro-controller based data logger records the barometric pressure, and filter and air temperature. In addition to this, the PC based software provides an intelligent report of the system parameters.

Advance feature of AP 550 EL :

  • The sampling rate is held constant at 1m3/hr by a microprocessor based electronic flow
  • controller that automatically compensates for increasing pressure drop due to dust deposit on the filter
  • The APM 550 EL has an in-built USB Flash memory based data logger that records Filter ID, air temperature, filter temperature, barometric pressure, flow rate, Coefficient of Variation (CV) and also totalizes and records the volume of air sampled

Specifications:
Size selective inletsPM 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, 50 Hz 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
