Thermo Scientific 5014iQ Beta Particulate Monitor

5014iQ is a monitor that determines particulate mass in ambient air by looking at how much collected particles attenuate beta radiation. It can measure PM-2.5, PM-10, PM-1 and TSP; the measurement range is 0-10,000 µg/m³. The mass measurement is verified to ±5 percent accuracy with an SI-traceable mass foil set. The instrument heats only when needed, removing humidity effects and preserving volatile aerosol.

• US EPA PM-10 equivalent (EQPM-1102-150) and PM-2.5 equivalent (EQPM-0609-183) monitor approval.
• The filter tape advances to a clean spot according to user-defined mass accumulation and flow limits.
• Resolution 0.1 µg/m³; averages of 60-3,600 seconds and 24 hours.
• Sample flow 1 m³/h (16.67 L/min), selectable between 14-20 lpm.
• MODBUS, TCP/IP, Gesytec, streaming data and NTP protocols over Ethernet.

3 USB and 1 gigabit Ethernet are standard; optional analog and digital I/O and serial ports can be added.

Because the filter tape advances automatically, the instrument can run unattended for long periods. Tape advance criteria are user-defined, so the tape changes more often during periods of heavy particle loading.

Tetra includes tape changes, flow calibration and mass foil verification for 5014iQ in the measurement campaign's maintenance calendar. Tape, filter and pump parts can be supplied domestically.
