Indoor Air Quality (IAQ) Meters, Monitors

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

For 20 years, GrayWolf’s highly advanced, professional indoor air quality (IAQ) meters and instruments have made proactive IAQ and green building surveys efficient and easy to conduct. Occupant wellness is rapidly gaining awareness as a win-win for occupant health and productivity, and for building owners’ bottom line. 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.

Prefer an indoor air quality meter for walk-thru surveys? Want an IAQ monitor for use as a long-term (hours/days/weeks) trend data logger? Both modes are necessary for thorough indoor air quality investigations; commercial, industrial, institutional or residential. 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 all-new DirectSense II probes incorporate plug-and-play sensors, up to 8 in one probe, allowing you to easily adapt to changing IAQ requirements.

DirectSense II Probe in use during IAQ survey

Connect 1 or 2 DirectSense II multi-sensor probes; via cable or via Bluetooth wireless (as shown).

DirectSense II Multi Gas Meter

The DirectSense II smart probes accommodate plug-and-play sensors, including the best on the market for IAQ applications.

Up to six (6) low detection limit, fast response gas sensors plus %RH and °C/°F in a single probe.
