Typical Measurement Range
Teledyne API T640(X): 0.1–10,000 µg/m³ — same analyzer as PM10 (see above), which measures PM10, PM2.5, and PM10-2.5 simultaneously.
Service coverage isn’t limited to the instruments above.
The instruments above are the ones we most frequently sell and support, but our service capability isn’t limited to this list. Ambilabs services any instrument carrying a Federal Equivalent Method (FEM) designation under 40 CFR Part 53, per the EPA’s official List of Designated Reference and Equivalent Methods.
