Nextriv Sense IAQ Pro9-in-1 air quality station

What it is for

This is the flagship of the Sense family — nine parameters in one device and the only sensor in the series with a swappable "ninth sense": your choice of formaldehyde (HCHO) or ozone (O₃). Formaldehyde is the silent lodger of freshly fitted-out interiors — it keeps off-gassing from furniture, adhesives and lacquers for months after a renovation. Ozone, in turn, can be a by-product of disinfection and electrical equipment. Nextriv Sense IAQ Pro was built for facilities that treat air quality as a commitment: offices aiming for healthy-building certifications, medical facilities, premium schools and investors accountable for ESG.

Its formal status sets it apart, too: the device carries a compliance mark of the WELL healthy-building certification programme — independent confirmation that it supports the standard's requirements in the areas of air quality, comfort and well-being. For a building manager that is a ready-made argument in WELL, LEED or BREEAM certification processes: the sensor's data is credible evidence. Property operators base certifications of entire building portfolios on data from sensors of this class.

Structurally it is a device that is "always on duty": permanently powered via USB-C, it operates in continuous radio-listening mode — it executes remote commands instantly, without waiting for a transmission window. That makes it suitable not only for measurement, but also for real-time control scenarios.

Sensitivity makes the difference here: the formaldehyde path covers 0–1.25 mg/m³ with 0.01 mg/m³ resolution — enough to pick up emissions from new furniture long before the odour detection threshold. The ozone variant measures 0–10 ppm with 0.01 ppm resolution. USB-C-only power is a deliberate design decision: the particulate and gas sensors plus continuous listening demand constant energy — in return, the device never skimps on measurement quality. The enclosure stays the same as across the whole series — a fleet of different variants looks identical on the walls.

Usage scenarios

• Premium residences: sensors of this class wired into a smart-building platform cut energy use and shorten HVAC troubleshooting time — with better humidity control even in a demanding climate.
• Self-storage facilities: sensor data as evidence in LEED certification of entire facility networks.
• Freshly fitted-out office: formaldehyde monitoring documents that post-renovation concentrations dropped to a safe level before the team moves in — in black and white, in data, not in the contractor's assurances.
• Clinic using ozone disinfection: the O₃ variant confirms that after an ozonation cycle the concentration has returned to normal before patients enter the consulting rooms.
• Shopping centre: sensors of this class integrated with building automation steer air quality for customers and staff while optimising energy.
• Campuses and public buildings: monitoring of energy performance and air quality — sensor data as input for municipal policies and smart-city projects.

Key features

• WELL programme compliance mark — independent validation of suitability for healthy-building certification; a strong argument in tenders and ESG reports.
• Swappable ninth sensor: formaldehyde (electrochemical cell, approx. 6-year lifetime) or ozone (approx. 2 years) — one platform, two risk profiles.
• CO₂ measured with photoacoustic technology — a compact, precise alternative to classic optical paths.
• Permanent power + continuous radio listening = instant response to remote commands; the device is fit for control, not just measurement.
• The full PM2.5/PM10 particulate package (laser scattering) as standard.
• Large 4.2″ e-ink display with emoticons, "traffic lights" and configurable layouts; built-in acoustic alarm.
• 18,000 records of tamper-proof history + retransmission — certification data with no gaps.
• Setup with a tap of a smartphone (NFC) and remote reconfiguration of entire fleets.
• Anti-theft mounting hardware — important in public spaces.

In the Nextriv system

Nine metrics in the Nextriv platform means nine sets of alarm thresholds — two warning and two critical each — with event codes, statuses and team comments. Notifications travel on the channel that fits the recipient (e-mail, SMS, web push, Discord, MS Teams, in-app sound), and escalation policies make sure a post-renovation formaldehyde alarm doesn't get stuck in someone's inbox. Dashboards line up all nine metrics side by side, floor plans with markers show exactly where the problem arises, and a sensor silent for longer than twice its reporting interval gets an offline status. XLSX/CSV exports feed external ESG reporting systems.

For certified facilities the reports are key: PDFs with statistics and percentiles, threshold-compliance sections and a cryptographic signature (SHA-256 with a QR code and a verification address) — a document whose authenticity an auditor can check on their own. The report schedule delivers them on a recurring basis, and measurement history of up to 5 years covers a full recertification cycle.

Typical deployments

• Commercial buildings: monitoring for WELL/LEED/BREEAM certifications and ESG reporting — continuous data instead of one-off audits.
• Healthcare: ozone checks after disinfection cycles in clinics and consulting rooms, before patients return.
• Schools: the full air quality picture on the display and in reports — including formaldehyde after classroom renovations.
• Laboratories: continuous recording of nine parameters at a single measurement point, with instant response to commands.
