Teledyne API is excited to unveil the latest addition to our ambient particulate monitoring product portfolio: The Model T640 PM mass monitor. Delivering continuous, real-time PM mass measurements using innovative broadband spectroscopy, the T640 comes with high resolution, fast response, low power, and effortless operation.

Measurement Principle: Broadband spectroscopy using 90° white-light scattering with Polychromatic LED
Particle size resolution: 256 sizes over 0.18 – 20μm range, combined to 64 channels for mass calculation
PM Mass Measurements: PM10, PM2.5, and PM10-2.5 simultaneously
PM Mass Resolution Measurement Range: 0.1 - 10,000 μg/m3
Mass Measurement & Display Resolution: 0.1 μg/m3
Precision: ±0.5 ug/m3 (1-hr average)
Lower Detectable Limit: <0.1 ug/m3 (1-hr average)
Data Rate: 10s to 48hr (user selectable)
Mass Concentration Accuracy: Exceeds US EPA PM10 FEM and Class III FEM PM2.5 performance requirements for additive and multiplicative bias compared to FRM samplers
Flow Rate: 5.0-lpm sample flow (Standard model); 11.67-lpm optional bypass flow (with option 640x)
Flow Accuracy: Within ±1%; (Typically within ±0.5%)

Operating Temperature: 0 - 50°C, non-condensing
Ambient Temperature: -40 - 60°C
Ambient Relative Humidity: 0 - 100%
Sample Humidity Control: 24VDC, 90W (max) heater controlled to 35% RH
Weatherproof enclosure required with 0 - 50°C, non-condensing environmental control
Requires only 10-min warm-up time

T Series analyzer interface with full touch screen display and NumaView™ premium operating software and NumaView™ remote software
4Gb memory allows for >1 year of internal data storage
Front Panel USB Ports: 2x type-A Peripheral Ports
Ethernet Communication (supports TCP/IP Modbus and HTTP polling protocols)

T640 instrument: 100 - 230VAC 50/60Hz, Power consumption < 120W @ 120VAC
External pump(for optional bypass flow - option 640x): 100 - 120VAC 60Hz or 220-240VAC 50/60Hz, Power consumption <360W @ 120VAC
