Indoor Air Quality Instruments
iAQ-Pro
15-Parameter Handheld IAQ Field Instrument
Measure particulate matter, gases, temperature, humidity, and more — all in one field-ready device with 72-hour battery life.
ARG Instruments
One instrument. Every parameter that matters.
The iAQ-Pro measures PM1, PM2.5, PM4, PM10, CO₂, TVOC, NOₓ, CO, temperature, relative humidity, barometric pressure, and sound level — plus optional e-Pod expansion modules for Radon and moisture.
Built for the Field
Everything a field instrument should be.
Designed for IAQ professionals, industrial hygienists, and environmental consultants who need accurate data — anywhere.
Measure What Matters
PM1, PM2.5, PM4, PM10, CO₂, TVOC, NOₓ, CO, temp, humidity, pressure, and sound. Expandable with e-Pod modules for Radon and moisture.
72-Hour Battery Life
6500 mAh LiFePO₄ battery powers a full three-day field survey without recharging. Charges via USB-C.
5″ Touchscreen
Full-color 5-inch display shows live readings, trends, and alerts. Intuitive touch interface — no laptop required in the field.
Cellular + Wi-Fi
Automatic cloud sync via cellular (nRF9160) or Wi-Fi. OTA firmware updates. GPS location tagging on every reading.
