Assessing thermal comfort and indoor air quality (IAQ) requires simultaneous measurement of multiple environmental parameters. Our portable instruments for measuring WBGT, PMV/PPD, globe temperature, CO2, and related climate indices give you a comprehensive picture of the indoor environment in a single device. Designed for workplace assessments, building diagnostics, and HVAC evaluations, they allow you to identify health risk, comfort issues and air quality problems quickly and accurately on site.
