Kestrel Heat Stress Meters & Instruments Range

As our climate changes and extreme weather events become more frequent, the need to measure heat stress accurately at an exact location is now an essential part of ensuring the safety of employees, soldiers, athletes and animals. The continuous supply of real-time Heat index and Wet Bulb Globe Temperature (WBGT) data is a key asset in managing heat stress and the associated risks.

Kestrel Meters now include specialist data streams for heat stress management measuring Wet Bulb Globe Temperature (WBGT), Thermal Work Limit (TWL), heat index, temperature, humidity and much more, all in a handheld portable unit.
