Measures Simultaneously PM 1, 2.5, 4, 7, 10 & TSP & Particle Size Ranges 0.5 to 5.0 µm

 Flow Rate 2.83 l/m, Battery Operated, Light Scattering Technique

The AEROCET 531S is a full–featured, battery operated, hand-held mass monitor or particle counter. This amazing unit simultaneously measures 6 mass concentration ranges  or five particle count sizes (0.3μm, 0.5μm, 1.0μm, 5.0μm and 10μm). View sample history data in either mode.

KEY FEATURES

Aerosol Mass and Particle Count Measurements in a Single Hand held Unit
The AEROCET 531S is a small, hand-held, battery operated, and completely portable unit. This unit provides both particle counts and mass PM measurements.

Six Mass Ranges and Five Particle Sizes
Six important mass size ranges (PM1, PM2.5, PM4, PM7, PM10, and TSP) are displayed in mass mode as well as five popular particle sizes in count mode.

Tailored Mass Conversion
The particle counts from eight size ranges are converted to mass using a proprietary algorithm for typical-density aerosols. Accommodation for special particulate with different densities is provided through user-programmable “K‐factors.”

Flexible Data Interfaces
The AEROCET 531S stores over 6,000 records. These records can be viewed on the display, or transferred to a computer via USB or RS232. Our included Comet download utility makes file transfers easy. Import sample data into a spreadsheet or print hard copies using the optional G3115 printer.

Temperature and Relative Humidity Option
A plug-and-play option that immediately adds ambient temperature and relative humidity capabilities to the displayed and logged data

Applications:
•Controlled Environments
•Industrial/Occupational Hygiene
•Indoor Air Quality
•HVAC Applications
•Hospitals & Clinics
•Filter Testing
