JANTYTECH WBGT Index Meter

Environmental Heat Stress Monitoring

Wet Bulb Globe Temperature (WBGT) Index Meter

Understand More Than Air Temperature

WBGT accounts for air temperature, humidity, wind speed, and radiant heat to provide a more complete picture of environmental heat stress.

Air Temperature

Direct ambient dry-bulb temperature measurement.

Humidity

Relative humidity directly influences evaporative efficiency.

Wind Speed

Airflow affects convective heat dissipation.

Radiant Heat

Direct solar radiation and thermal heat reflection from site materials.

Three Temperature Components. One WBGT Index.

Specialised sensors capture the fundamental vectors of ambient heat stress directly from the environment.

Dry-Bulb Temperature

Measures standard ambient air temperature shielded from direct solar radiation.

Natural Wet-Bulb Temp

Reflects evaporative cooling from a wetted sensor exposed to natural airflow.

Black-Globe Temperature

Measures direct solar exposure and cumulative radiant energy inside a standard globe.

Relative Humidity

Provides critical ambient moisture data to contextualise dynamic heat metrics. Measured separately from the three temperature components.
