Airflow & IAQ — Measure Comfort, Prove Results

From balancing a new fit-out to fixing a stubborn hot spot, this Airflow & IAQ range helps you see what the room is really doing. With easy-to-read instruments and tidy carry cases, you’ll work faster, document clearly, and keep homes, offices, and classrooms feeling fresh and evenly conditioned.

Why this range works on real Aussie jobs

Versatile tools, clear answers: Capture supply and return readings, verify room pressurisation, and check ventilation rates with the right mix of hoods, probes, and indoor air quality meters.
Built for everyday reliability: Rugged housings, stable sensors, and simple interfaces mean less fiddling on ladders and more time solving the brief.
Smart presentation, tidy workflow: Compact frames and clean displays look professional on site and make reports easier to explain to clients and consultants.
Comfort you can prove: Balance air like a pro, reduce noise complaints, and back it up with data your customers understand.

Explore the essentials

Airflow hoods & balometers — quick capture of supply/return volumes for balancing and handover.
Anemometers — pinpoint grilles, diffusers, and duct velocities when you’re fine-tuning throw patterns.
Manometers — confirm filters and coils are right by tracking static pressure and fan performance.
IAQ meters — check CO₂, particulates, temperature, and humidity to keep spaces healthier and more productive.

Where these tools shine

Commissioning & balancing: Verify volumes at each outlet and document final settings for a smooth handover.
Troubleshooting comfort issues: Track drafts, low flow, or poor ventilation and fix the root cause—not just the symptom.
Maintenance & energy: Spot rising pressure drops early, restore airflow, and help systems run quieter and cheaper.
Compliance & reporting: Record IAQ baselines and airflow evidence for auditors, builders, and facility teams.

Practical kit with a clean, professional look

These instruments are designed to be handled all day—sleek frames, clear screens, and cases that protect your investment. They look the part in front of clients and make your data simple to understand in a quick toolbox talk.

Airflow & IAQ – Frequently Asked Questions

Quick, practical answers to the questions Aussie tradies ask most—so you can solve comfort issues faster and document results with confidence.

What’s the best airflow hood for room balancing in Australia?

Choose a hood with stable, low-drift sensors, multiple frame sizes, and a durable case. A good hood should capture both supply and return volumes with minimal setup and provide steady readings in real site conditions.

How do I measure supply air volume at a diffuser quickly?

Use a capture hood for direct L/s readings on grilles and diffusers. If using a vane or hot-wire, take several passes, average the face velocity (m/s), and multiply by the grille’s effective area to estimate flow.

My static pressure is too high after a filter change—what should I check?

Confirm filter orientation and MERV rating, compare pre/post filter pressure, and inspect for blocked coils or closed dampers. Trending external static helps catch issues before fan power and noise rise.

How much outside air do I need for an office? Can CO₂ help?

CO₂ is a handy proxy for ventilation effectiveness. Aim to keep indoor CO₂ close to outdoor background during occupancy. Log CO₂, temperature, and humidity, adjust outdoor air and balancing, then verify the trend stabilises.

Anemometer vs airflow hood—what’s more accurate?

A capture hood delivers quick, repeatable volume at the face. An anemometer excels at diagnostics, velocity profiling, and duct traverses. Most commissioning jobs use both: hood for volumes, anemometer for fine-tuning.

What IAQ meter is recommended for schools and clinics?

Pick a meter that logs CO₂, temperature, humidity, and particulates (PM), supports data export, and has clear alarms. Stable sensors and easy calibration are worth prioritising.

How do I diagnose hot and cold spots in open-plan spaces?

Map diffuser flows with a hood, check throw and induction patterns with an anemometer, confirm return capture, then verify fan performance via static pressure. Balance dampers and recheck comfort at occupant level.

Do I need a balancing checklist?

Yes. A simple checklist speeds handover and reduces callbacks. Include outlet IDs, target vs measured volumes, damper settings, static snapshots, and a short summary of corrective actions.

What PM2.5/PM10 levels should I expect in a well-ventilated space?

Outdoors varies with weather and traffic; indoors, good filtration and fresh air should keep PM trends low and stable. Log indoor/outdoor comparisons and adjust ventilation or filtration where trends drift.

Why doesn’t my return grille velocity match the design flow?

Face velocity alone can mislead due to grille type, approach, and effective area. Confirm with a capture hood or a duct traverse, and check filter loading and coil condition with a quick static pressure check.

Any tips to present findings clearly to clients?

Keep it visual and brief: a one-page outlet table with hood readings, a pressure snapshot, and a simple IAQ trend chart. Finish with recommended settings and maintenance notes.
