GrayWolf’s fundamental design directive has been to make our product technically superior, yet intuitive and Easy-To-Use.

GrayWolf utilizes state-of the-art sensors for the application, and provides an advanced user interface that makes documentation of environmental surveys and detailed report generation easy and efficient.

Over 30 parameters are now available to measure and data-log with GrayWolf’s DirectSense® probes, AdvancedSense® meters and WolfPack® area monitors; including VOCs, carbon dioxide, airspeed, particulates, %RH, differential pressure, ozone, ammonia, formaldehyde and more.

Primary applications addressed include Indoor Air Quality (IAQ), Occupational/Industrial Hygiene, HVAC, Facility Management, Green Buildings, Toxic Gas, IVF and Ambient air measurement.

In 2004 GrayWolf purchased the Solomat product line of 'classical' IAQ Monitors, Digital Micro-manometers and Air Velocity Meters. These instruments, now sold and serviced under the GrayWolf label, are available with GrayWolf's highly advanced data analysis and report generation software.

GrayWolf continues to develop new, cutting edge products. Most recently, 2015 has seen the introduction of the unique, highly versatile AdvancedSense Pro embedded computer based environmental meter. At a time that many companies in our industry won’t support instruments >7 years old, clients with 15+ year-old GrayWolf probes are able to upgrade to use them with this powerful new platform. We continue to significantly update our application and reporting software, as well as our GrayWolfLive cloud-based webhosting for remote access to data (via your iPad, Android phone, etc.) from GrayWolf's WiFi enabled monitors. And additional sensors and new platforms are under development.
