Indoor Air Quality Meters
GrayWolf's IAQ meters provide precise measurement of pollutants like VOCs, CO2, and particulates. These tools help identify ventilation issues and validate air quality improvements in schools, hospitals, and offices. Our systems combine portability with advanced sensors and cloud connectivity for real-time monitoring and reporting.
Toxic Gas Detectors
Our toxic gas detectors measure hazardous substances including ozone, ammonia, and hydrogen sulfide. These instruments support industrial hygiene and safety compliance through handheld or continuous monitoring. Bluetooth and cloud integration enable remote data access and multi-gas analysis for complex environments.
Formaldehyde Monitors
GrayWolf's formaldehyde monitors offer low-level detection (down to 10ppb) for IAQ assessments. The FP-31G meter provides rapid results with no warm-up time, while DirectSense XM probes enable continuous monitoring. These tools meet LEED and WELL certification requirements for indoor pollutant screening.
Particulate Meters
Our 6-channel particulate meters measure PM0.5 to PM10 levels with precision pumps and size-resolved detection. These instruments integrate with IAQ systems for comprehensive air quality assessments. Data logging and cloud connectivity support compliance with environmental regulations and health standards.
Cloud Software Platforms
GrayWolfLive cloud platform enables real-time access to air quality data from any device. This system supports trend analysis, automated reporting, and multi-site management through secure dashboards. Integration with mobile apps and desktop software ensures seamless data flow for facility managers and consultants.
