Particulate & Dust Monitors
TSI DustTrak real-time light-scattering laser photometers for aerosol/dust mass-concentration monitoring. DustTrak II reports one user-selected size fraction; DustTrak DRX reports PM1/PM2.5/PM4/PM10/Total simultaneously; Environmental models (8540/8543) add a weatherproof enclosure for outdoor/fence-line use, and the M variants add MCERTS certification.

On the platform
What the TSI DustTrak Gets From Aethair
Connected through Thiamis, its readings arrive in the same Environet account as Aethair's own monitors.
Live data and alerts
Environet shows the instrument live and alerts the people you choose by email, SMS, and webhook, at the thresholds you set. Noesis sets up a dashboard, a report, or an alert from a plain-text request.
Compliance reports
Aethair Reports produces scheduled or on-demand reports from the instrument's readings, as a PDF or secure link. Templates cover Aethair Blue, WELL v2, cabin air (ISO 23875), and the CMS-2567 healthcare codebook (ASHRAE 170), or you can report against custom limits such as OSHA PELs, NAAQS, EPA guidance, or your own program limits.
Dashboards and the app
Environet dashboards and the Aethair App show the instrument's readings just like any Aethair device. The occupant-facing Aethair Dashboards status display is built around Aethair IAQ and Aethair PRO.

Questions
TSI DustTrak FAQ
How does the DustTrak measure dust concentration?
It is a light-scattering laser photometer: the aerosol is drawn through a sheath-air optics chamber and the 90-degree light scattered from a laser diode is converted to a real-time mass concentration in mg/m3. A user-inserted 37 mm gravimetric filter cassette lets you collect a reference sample for custom (gravimetric) calibration.
What is the difference between DustTrak II and DustTrak DRX?
DustTrak II (8530, 8530EP, 8532) is single-channel: it reports one user-selected size fraction, set by the inlet impactor (PM1, PM2.5, Respirable/PM4, or PM10), as a single mass concentration. DustTrak DRX (8533, 8533EP, 8534, and the Environmental 8543/8543M) uses a size-segregated technique to report PM1, PM2.5, PM4 (Respirable), PM10, and Total PM simultaneously from one sample.
What do the EP models add?
EP (8530EP, 8533EP) is a desktop unit with a low-power external pump for continuous, unattended 24/7 monitoring over days to months. The standard desktop (8530, 8533) uses an internal pump suited to shorter work-shift or indoor-air-quality sampling.
What do the M models add, and which fraction is each certified for?
The M models are the MCERTS-certified DustTrak Environmental builds for UK/EU regulatory use, in a weatherproof enclosure with built-in auto-zero. 8540M is certified for PM2.5, 8542M for PM10, and 8543M is the DRX build certified for both PM2.5 and PM10.
Does the integration report a Short-Term Exposure Limit (STEL)?
Yes. The driver supports a 15-minute STEL alarm per size fraction (PM1, PM2.5, PM4, PM10, Total); when a per-fraction setpoint is exceeded it posts the 15-minute average. STEL is an alarm value, not a separately measured parameter.
How does the Thiamis integration talk to the instrument?
Over RS-232 serial at 9600 baud, 8-N-1. On connection the driver auto-detects the model and polls the instrument each interval; the model determines whether one mass value (single-fraction) or five (DRX) are ingested.
