3340 Laser Aerosol Spectrometer

If you cannot find the part number in the documentation please provide detail. Specific to this item, it could include part number or application detail, (ex. 20 meters of cable, or 20 litres of volume)

TSI's Laser Aerosol Spectrometer Model 3340 is a high sensitivity, high resolution general purpose aerosol particle sizer. This 'turn on and measure' instrument allows users to easily measure a size range of 0.09 (90 nm) to 7.5 µm. Complete size distributions are measured in less than a second by simply powering up and sampling.

The 3340 Laser Aerosol Spectrometer is suitable for a wide range of applications; Indoor Air Quality - Atmospheric Research & Environmental Monitoring - Inhalation Toxicology & Exposure Monitoring - Filter Testing

The 3340 is a handy tool to have monitoring your filters or your processes; measuring in a lab; or sampling on field campaigns. It's as useful as your primary aerosol tool, but the 3340 can also provide valuable supplemental information to aerosol measurements based on other sizing techniques (i.e. SMPS, APS, CPC, FMPS, etc.).

Features and Benefits
• Ultra-high Sensitivity & Superior Resolution
• Dynamic Size Range: 0.09 to 7.5µm
• Typical Resolution is within 2.5% of the particle diameter at 0.1µm
• 18,000 part/cm3 at 0.01 L/min

Valuable Addition to Your Aerosol Tool Kit
The 3340 is a handy tool to have monitoring your filters or your processes, measuring in the lab, or sampling on field campaigns. It’s as useful as your primary aerosol tool, but the 3340 can also provide valuable supplemental information to aerosol measurements based on other sizing techniques (i.e. SMPS, APS, CPC, FMPS, etc).

Ease of Use
• On-board Windows®-based PC with Excel. No need to procure and dedicate a laptop to operate your instrument
• Intuitive LabView™ based software

On-Board PC
The Laser Aerosol Spectrometer features an internal Windows® based PC loaded with Microsoft Office®. No need to procure and dedicate a laptop to operate your instrument. A 30 GB hard drive, keyboard and mouse, and a 10" color LCD display are included–just like your personal PC. Microsoft Excel® data analysis can be performed on the fly or data can easily be transferred via Ethernet, CD or USB port.

Flexibility
• 100 particle size channels: user configurable. Users can zero in on a specific size range or match the resolution of a different instrument
• User adjustable flow rate: Allows the user to optimize the flow rates for a specific application at the click of a mouse
• State-of-the-Art Optical & Detection System
• Patented wide angle optics and intercavity laser
• Highly sensitive photodetectors, automated gain ration adjustment and laser reference compensation

Applications
• Filter Testing
• Indoor Air Quality
• Atmospheric Research & Environmental Monitoring
• Inhalation Toxicology & Exposure Monitoring
