The Thermo Scientific TEOM 1405-F monitor provides continuous ambient PM measurement with volatile and non‑volatile fraction accounting.
The TEOM 1405-F is a continuous ambient air monitor that combines a Filter Dynamics Measurement System (FDMS) and a TEOM mass sensor in a single, network‑ready cabinet with a touch‑screen interface. It automatically generates mass concentration measurements (μg/m³) for PM‑10, PM‑2.5 and PM‑Coarse, accounting for both volatile and non‑volatile particles.
Key specifications include a measurement range of 0‑1,000,000 μg/m³, 0.1 μg/m³ resolution, and ±0.75% accuracy. The unit offers Ethernet with embedded FTP server, USB, RS‑232/RS‑485 communications, analog outputs, and contact‑closure alarms. It operates with a main flow rate of 3 l/min, supports data logging of up to 500,000 records, and is designed for temperatures from –40 °C to 60 °C (sensor enclosure 8‑25 °C).

It measures PM‑10, PM‑2.5, and PM‑Coarse (PM10‑2.5) mass concentrations in ambient air.
The unit provides Ethernet with an embedded FTP server, USB, RS‑232, RS‑485, plus analog outputs and contact‑closure alarm circuits.
The sampled air temperature may vary between –40 °C and 60 °C, while the sensor and control units must be protected within 8 °C to 25 °C.
