The 1405-DF TEOM Monitor simultaneously measures PM Fine (PM-2.5), PM Coarse and PM-10 mass concentrations. Consisting of two Filter Dynamics Measurement Systems (FDMS) and two TEOM mass sensors housed in a single-cabinet, network-ready configuration that includes control system with touch-screen user interface. The TEOM 1405-DF distinguishes itself from other PM measurement methods by utilizing a direct mass measurement that is not subject to measurement uncertainties found in surrogate techniques. It provides a self-referencing, NIST-traceable true mass measurement.
Key Features:- Utilizes TEOM technology to provide direct mass measurements and FDMS to account for volatile and nonvolatile PM fractions
- Designed to meet US and International Particulate Monitoring Regulations
- Compact, stand alone, network-ready unit which utilizes a virtual impactor to measure PM Fine (PM-2.5) and PM Coarse concentrations with the ability to output PM-10
- Touch-screen GUI interface quickly and intuitively accesses system status, TEOM data, settings, and instrument conditions
- A service screen provides access to software wizards which walk the user through calibration and maintenance procedures with detailed instructions and pictures
Standard System Configuration:- TEOM sensor and control unit housed in a single compact enclosure
- Menu-driven software for user interaction via a touch-screen display
- ActiVol flow control using Automatic Mass Flow Controller(s) and supplied Ambient Temperature and Ambient Pressure Sensors
- ePort software for local or remote communication, USB port for automated download
- System configurations include PM-10, PM-2.5, and PM-1
Data Averaging
- Real-time Mass Concentration Average: One hour rolling average updated every six minutes
- Long-Term Averaging: 1, 8, 24 hr.
Sample Flow
Activol flow control system uses the mass flow sensors and the measured ambient temperature and pressure to maintain constant volumetric flow rates.
Filter Media
- Sample Filter: Pallflex TX40, 13mm effective diameter
- Sample Conditioner Filter: 47mm diameter housed in an FRM-style molded filter cassette, maintained at 4°C; suitable for collecting and archiving time-integrated PM samples for subsequent laboratory analysis
Sample Conditioning
- Nafion dryer lowers the main flow relative humidity and allows for mass transducer operation a 5°C over the peak air monitoring station temperature
- Purge Filter Conditioner contains a heat exchanger that maintains the temperature of the main flow and particle filter at 4°C to efficiently filter the volatile and nonvolatile PM in the sample
Includes: - Connecting and interface cables and vacuum pump
- Consumables for average first year operation (ambient) excluding pump & FDMS dryer refurbishment part
- Pallflex TX40 Filter, 13mm effective diameter
Compatible with: - Streamline Pro MultiCal System
- Complete Outdoor Enclosure
