Indoor Air Quality (IAQ) Meters, Monitors

For handheld, semi-permanent and long-term IAQ measurement

For over 20 years, GrayWolf’s highly advanced, professional indoor air quality (IAQ) meters and monitors have made proactive IAQ and green building surveys efficient, and easy to conduct.

Reliably measure key specific pollutants (VOCs, CO, O3, NO2, NH3, HCHO, etc.; choose from 25+ gas sensors), as well as Particulate, Ventilation Rates (CO2 and Airflow), Differential Pressure (DP) and more. High performance, fast response instrumentation for consistent use over portable, long-term and continuous IAQ testing applications.
Occupant wellness is rapidly gaining awareness as a win-win for occupant health and productivity, and for building owners’ bottom line.
COVID-19 has enhanced the need for measurement of ventilation rates, airflow, pollutant pathways and validation of fixed sensors for specific IAQ parameter monitoring in schools, hospitals, public buildings, workplaces, and other indoor facilities of all types.
GrayWolf IAQ meters, monitors and instruments optimize the balance between facility energy efficiency and occupant health, comfort and productivity.
Identify potential IAQ issues before they become problems and respond immediately to complaints with the highly accurate and most intuitive portable IAQ meters, monitors and testing devices available today.

The DirectSense II smart probes accommodate true plug & play sensors (up to 8 in a single probe), optimized for high-end, accurate measurements targeted for commercial, industrial, research, and institutional IAQ applications.

Comprehensive IAQ Meters / Monitors

Prefer an indoor air quality meter for walk-thru surveys and outdoor air comparative spot checking? Want an IAQ data-logger for use as a long-term (hours/days/weeks) trend logger? Both modes are essential for thorough commercial, industrial, institutional, or residential indoor air quality investigations. And how about continuous IAQ monitoring?

GrayWolf’s instruments are designed to provide a full solution, from measurement through reporting, for a comprehensive range of IAQ test and measurement needs.

The high quality IAQ sensors utilized in GrayWolf’s instrumentation also make this equipment the top choice for IAQ/IEQ research projects, for government agencies conducting critical building indoor air quality tests, for validation of low-cost air quality meters/monitors and for many other applications.

And the versatility of the DirectSense II probes and connective platforms allow you to easily adapt your high-end investment to changing IAQ requirements.
