TEOM series 1405 for particulate monitoring

Lear Siegler, in conjunction with Thermo Fisher Scientific, has released the TEOM series 1405 for ambient particulate monitoring, featuring modernised electronics and a touch-screen user interface packaged in a single cabinet.

The device addresses the need to provide accurate PM-2.5, PM-10 and PM-coarse measurements as defined in new US EPA standards and methods. Furthermore, the product line, which replaces the TEOM 1400ab monitor, enables users to achieve multiple measurements in a single instrument.

The device is available in four models providing one to three measurements: PM-10, PM 2.5 (fine) and PM-coarse (PM10-2.5). In addition to providing PM measurements, users can choose to add a Filter Dynamic Measurement System (FDMS) option to account for volatile and semi-volatile fraction.

The models include: TEOM 1405 ambient particulate monitor; TEOM 1405-F ambient particulate monitor with FDMS; TEOM 1405-D dichotomous ambient particulate monitor; and TEOM 1405-DF dichotomous ambient particulate monitor with FDMS.

Each model in the series is delivered with a network-ready configuration and a user interface that allows quick access to system, data, settings and instrument conditions. The system's default data output consists of running 1 and 24 h average mass concentration updates every 6 mins and averaging times are user programmable from 30 mins to 23 h for the FDMS versions. The standard TEOM versions can be brought down to 10 min averages, depending on the application.
