| Aerosol Photometer | Light-scattering mass concentration indicating instrument with a threshold sensitivity of at least 10 to the negative third power microgram per liter for 0.3µm diameter DOP (Dioctyl Phthalate) concentrations over a range of 10 to the fifth power times the threshold sensitivity. Photometers may include hand-held remote meter probes that can scan for airborne contaminants in HEPA filters, in penetrations around frames, seals and plenums, and in hoods and work stations. |
