Formed in 1998, GrayWolf is the worldwide market leader in high performing, portable and semi-permanent indoor air quality instrumentation, with distributors in 40+ countries and a strong presence in other environmental instrumentation markets. We offer advanced sensor, software and instrumentation technology, employing the power of mobile and embedded computers for superior environmental test instrumentation. Our products are designed to diagnose opportunities to improve the productivity, health and safety of people, while increasing energy efficiency in buildings and identifying 'green' solutions for the planet. GrayWolf's management (with over 100 years' experience in the industry between the 4 founding partners), along with our highly experienced service and sales staff, have brought our extensive environmental instrumentation knowledge to bear to supply solutions that overcome the obstacles that limit traditional manufacturers.

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 AdvancedSense® meters, DirectSense® mobile PC based products, 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, energy efficiency, 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.
