Aethair monitors
Aethair PRO
Industrial-Grade Customizable Environmental Monitor for Indoor and Outdoor Use
Sensors
An Industrial Air Quality Monitor Built for Adaptability
90° laser particle detection (PM1, PM2.5, and PM10), hot-swappable gas sensor cartridges, a MultiSense cartridge, and a differential-pressure cartridge, in an aluminum alloy enclosure for indoor or outdoor operation, with Magnet, Wall / Locking, and Strap adapters for its mount and the optional Solar Panel Bracket. The built-in sensors and every cartridge are listed below, each linked to its catalog page.
Where it is used
Where Aethair PRO Runs
One device, set up for each by the cartridges it carries. Each tile opens its solution page.
Cabins and Equipment Fleets
Cabin pressure, CO₂, and VOCs in mining and heavy-equipment cabs, reported to ISO 23875, and in rail and transit fleets, with the same monitor in the cab and at the depot; Drummond Company runs Aethair PRO across its mining vehicle fleet in Colombia.
Outdoor and Ambient Networks
PM2.5, PM10, and total PM with gas sensor cartridges over 4G LTE, solar-powered where there is no mains, for city, roadside, and fenceline networks.
Wildfire Smoke
PM2.5 and PM10 from the built-in particle sensor across a regional network, solar-powered where there is no mains, with alerts at the thresholds you set.
Perimeter Monitoring
Dust, gases, and ppb-level VOCs at fencelines and site boundaries, with reports for compliance and community oversight.
Commercial Buildings
CO in garages and workplace air, room-to-room pressure via the differential-pressure cartridge, plus PM, noise, and comfort.
Medical Facilities
Aethair PRO combines built-in particulate, temperature, and humidity sensors with a VOC cartridge, plus a differential-pressure cartridge for rooms that need a pressure record. The CMS-2567 report checks temperature, humidity, and pressure against ASHRAE 170 for the surveyor.

What you get from it
What You Get From Aethair PRO
Every reading goes to the Aethair Cloud and appears in Environet. Each outcome below is a product you can read about.
Live data and alerts
Environet shows every device live and alerts the people you choose by email, SMS, and webhook, on a reading or its average over any window from 5 minutes to 30 days. Noesis fills in a dashboard, a report, or an alert from a plain-text request.
Compliance reports
Aethair Reports writes scheduled or on-demand reports, as PDF or secure link, from templates for Aethair Blue, WELL v2, cabin air (ISO 23875), and the CMS-2567 healthcare codebook (ASHRAE 170), or against custom limits such as OSHA PELs, NAAQS, or EPA guidance, each on the average you define. See a sample report.
Dashboards and the app
Aethair Dashboards put live readings on screens, online or by QR code, and the Aethair App puts them on phones. A public dashboard can show a work site's neighbors the air at its fence. See a live dashboard example.
Your data, stored until delivered
Aethair PRO caches readings on the device until they are delivered, so a connectivity outage delays readings instead of dropping them, and raw readings are stored exactly as the device sent them. Every reading is encrypted in transit to the Aethair Cloud and platform access is role-based. Live and historical readings export as JSON or CSV through the Environet API (OpenAPI 3.2). You own your devices and data, can grant partners controlled access, and readings are kept for as long as you need them (at least two years after a project ends) and deleted only at your request.
Calibrated, with little to maintain
Aethair PRO is calibrated before shipping against NIST-traceable reference standards and ships with a Performance Certificate: for each sensor checked against a reference device, it names that device and gives the correlation (R and R²) and the p75, p90, and p95 errors (an example, from an Aethair IAQ). There is no filter to change. Servicing means exchanging a pre-calibrated gas sensor cartridge when it is due, with a screwdriver and no recalibration on site, and firmware and configuration updates arrive over the air from Environet.
One account for every site
Every Aethair PRO, at every site, sits in the same Environet account as Aethair IAQ and Thiamis-connected sensors: one console, the same alerts, reports, and dashboards for every device.

Hot-swappable
Gas, MultiSense, and Expansion Cartridges
Aethair PRO has three kinds of cartridge socket, and each kind takes its own cartridge type. A full monitor carries two gas sensor cartridges, the MultiSense cartridge, and the differential-pressure cartridge.
- 2× Gas sockets. Any two of 17 pre-calibrated, hot-swappable cartridges, exchanged with a screwdriver and no recalibration on site.
- 1× MultiSense socket, inside, next to the gas sockets: the MultiSense cartridge, or a Custom MultiSense built to order for the kit.
- 1× Expansion socket takes the differential-pressure cartridge.
