New DustTrak II and DustTrak DRX Aerosol Monitors

1. 2008 Channel Partner Meeting New DustTrak II and DustTrak DRX Aerosol Monitors

2. Overview • What is the DustTrak? • New models • Features and benefits • Applications

3. What is the DustTrak? • The new DustTrak II and DRX Aerosol Monitors are • battery operated, • data-logging, • light-scattering laser photometers • that give you • real-time aerosol mass readings.

4. What is the DustTrak? • These monitors measure aerosol contaminants such as dust,smoke, fumes and mists. • They use a sheath air system that isolates the aerosol in the optics chamber to keep the optics clean for improved reliability and low maintenance. • Suitable for clean office settings as well as harsh industrial workplaces, construction and environmental sites and other outdoor applications.

5. Product Line – DustTrak II • Three new instruments have been developed • DustTrak II Model 8530 – basic single-channel (mass only) desk top aerosol monitor for IH/ENV/IAQ applications, replacement for the existing DustTrak • DustTrak II HC Model 8531 – basic high concentration (400 mg/m3) single-channel (mass only) desk top for Process Monitoring applications • DustTrak II Model 8532– basic single-channel (mass only) handheld aerosol monitor for IH/IAQ surveys and point source location applications

8. Product Line DustTrak DRX Aerosol Monitors • Two new instruments have been developed • DustTrak DRX Model 8533 – advanced multi-channel (mass/size fraction) desk top aerosol monitor for IH/ENV/IAQ applications • DustTrak DRX Model 8534 – advanced multi-channel (mass/size fraction) handheld aerosol monitor for IH/IAQ surveys and point source location applications

9. DustTrak DRX – the measurement • The DustTrak™ DRX Aerosol Monitors patent pending technology method combines both particle cloud and single particle detection to achieve size-segregated mass fraction measurements • It is not an optical particle counter (OPC), it is a photometer! • The DRX effectively combines both measurements in one instrument • The DRX size-segregated mass fraction measurement is superior to either a basic photometer or an OPC • The DRX delivers the mass concentration of a photometer with the size resolution on an OPC

10. DustTrak DRX – the measurement • The DRX can be set to display any of the following size fraction modes • IH Mode: Total PM, PM10, Respirable (≤4 µm) size fractions • ENV/IAQ Mode: Total PM, PM10, PM2.5, PM1.0 • All Mode: Total PM, PM10, Respirable, PM2.5, PM1.0 • Particle detection range: 0.1 - ~15 µm • Incorporates sheath air system • Internal pump for active sampling • No need for inlet conditioners • Measure any aerosol contaminant as long as it is in the particle detection range • Dust, smoke, fume, mist, etc.

12. DustTrak DRX - Features

13. DustTrak DRX Advantages Over OPC’s • Simultaneous measurement of size-segregated mass fraction concentrations • Size-segregated mass fraction data shown in real time • Can be used in high mass concentration environments • Ability to generate custom calibration factors using standard or advanced calibrations • Significantly reduces mass conversion errors using particle size and count data due to particle density, refractive index, and shape • Lower particle detection size range down to 0.1 µm

14. DustTrak DRX Advantages Over TEOM • Faster response time • Continuous and faster data acquisition rate (once per second) • Simultaneous measurement of size-segregated mass fraction concentrations • Size-segregated mass fraction data shown in real time • No need for multiple instruments for different size fraction measurements • No need for size-selective inlet conditioners • No consumables and low maintenance • Much lower cost of ownership – one instrument can do the work of many!

15. DustTrak II and DRX Optional Accessories • Auto Zero Module • External Battery Chargers • 6600 mAH Li-Ion batteries • 3600 mAH Li-Ion batteries • Field Service Kit • x8, internal sheath air filters • X2, replacement filter well covers

16. Auto Zero Module • The Auto Zero Module consists of a pump and a HEPA filter • The Auto Zero Module is attached to the inlet of the DustTrak along with a power cable • The interval of auto zeroing is user selectable from 15 minutes to 24 hours • Auto zeroing takes place in 1 minute, no data is recorded during this time • Over long periods of time the data missed during zeroing has insignificant contribution to overall average concentration
