GrayWolf Sensing Solutions

Formed in 1998, GrayWolf is the worldwide market leader in high performing, portable and semi-permanent indoor air quality instrumentation, with worldwide distribution and service, and a strengthening 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 (starting 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 complete solutions: accurate, reliable measurements, efficient documentation of surveys, through to detailed reporting.

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® 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.

GrayWolf continues to develop new, cutting edge products. The very smart DirectSense II range of true plug-and-play, multi-sensor probes, introduced in 2019, continue to have extra features added, most recently an internal WiFi and Bluetooth low energy card for remote connection via free apps for iOS and Android direct local connection. 2021 also saw the Zephyr LDP differential pressure module added just on the heels of the exceptionally accurate, yet wide range, Zephyr III handheld micromanometer. At a time that many companies in our industry won’t support instruments >7 years old, clients with 15+ year-old GrayWolf classical DirectSense probes have been able to upgrade to use them with our newest AdvancedSense meters and WIN 10 tablets.. 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, PC, etc.) from GrayWolf’s Wi-Fi enabled monitors or probes. And additional sensors and new platforms are under development.
