INTRODUCTION, SPECIFICATIONS,
APPROVALS, AND COMPLIANCE
The Teledyne API Model T640 with 640X Option is a real-time, continuous
particulate matter (PM) mass monitor that uses scattered light spectrometry for
measurement. The T640 measures 2.5 PM, and the 640X Option measures 2.5, 10,
and coarse PM.
