The Model T640 The next breakthrough in ambient particulate monitors. Dashboard 25.0 <io«,c Outside Temp PM MASS MONITOR - MODEL T640 ■ Continuous, real-time PM10 and PM2.5 mass concentration results ■ Simple set-up and 10-minute warm up time Superior measurement sensitivity and precision ■ Long autonomy and low power consumption Low maintenance and cost of operation ■ US EPA-approved TELEDYNE APIEverywhereyoulook"

Sophistication meets simplicity. Broadband spectroscopy combining advanced LED technology with well-understood light scattering theory. An innovative and robust algorithm produces accurate mass concentration data. Ethernet connectivity with TCP/IP MODBUS communications Robust measurement cell design provides Simple preventative Broadband vs. Laser Scattering Traditional monochromatic laser scattering approach yields uncertainty. The broadband approach provides an unambiguous scattered light signal for accurate measurements over a wide particle size range.

Do less and get more. The T640 delivers 1-min or better time resolution with exceptional sensitivity and precision. The instrument is very low maintenance and requires no sample media for minimal cost of operation. The T640 is completely self-contained and includes an internal 5-lpm vacuum pump, aerosol sample conditioner, and sample flow controller. The base model T640 is a US EPA-approved PM 2.5 Federal Equivalent Method. With the T640x option, the T640 can operate at 16.7-lpm and use the US EPAapproved PM10 inlet. This configuration is US EPA-approved as PM10 , PM2.5 , and PM10 - 2.5 A convenient...
