Miniaturized Optical Particle Counter

Model 9405

Features

The miniaturized Optical Particle Counter (mOPC) allows you to perform ultra-fast particle number size distribution measurements on-board Unmanned Aerial Vehicles (UAV) and other mobile platforms where high time resolution is critical. Capable of measurements every few seconds and a particle size range between 0.18 and 10 μm, the system is compact, light and uses minimal power. The mOPC offers high size resolution, with 10 size bins per diameter decade. The size range has been optimized to provide overlap with the Model 9404 mSEMS. Development of the mOPC is built upon BRECHTEL’s years of experience with traditional OPC instruments for high size resolution hygroscopic growth measurements and aircraft field studies. Deploy the 9405 in conjunction with our other portable instruments to get a more complete picture of the aerosol under study.

Key features:

  • Broad size range
  • High size resolution
  • Compact, lightweight, low power use
  • High/Low sample flow rate design
  • Sheath flow to improve detection and background
  • Self-contained with on-board data storage
  • No external pump required

Applications and Solutions

  • Mobile platform sampling: UAVs, Balloons, Aircraft, Vehicles
  • Personal exposure monitoring
  • Climate change field studies
  • Air quality monitoring

Software

Integrated software drives each ACCESS module from the inside – the built-in microprocessor and sensors are able to sense, control, and report on instrument performance. A serially-communicated stream of data provides real-time user access to all the fundamental operating parameters and measurement values. An on-board micro-SD card can be used to store data locally.

Add the Base Module option to your ACCESS package to benefit from a graphical user interface (GUI) that allows you to easily interact with the instrument so you can change parameter settings, configure outputs and view measurements on the screen of the PC. Multiple ACCESS modules can be connected via a micro-USB hub to the GUI allowing the system configuration to be easily changed. This feature also allows each of the connected modules to be remotely controlled via a single RS232 connection.The GUI software automatically recognizes which instruments are attached to the Base Module and adjusts accordingly. It is provided to facilitate configuration and monitoring of the ACCESS instruments on the

The GUI software automatically recognizes which instruments are attached to the Base Module and adjusts accordingly. It is provided to facilitate configuration and monitoring of the ACCESS instruments on the ground, but is not required to operate the unit and acquire data. The external GUI software is only available pre-loaded on a ruggedized tablet PC supplied by BRECHTEL.
