WBGT measurement with natural wet bulb temperature probe

Related instruments Temperature & humidity, Thermal comfort

An earlier post showed WBGT measurement with a combined temperature and humidity probe. With this configuration, the natural wet bulb temperature is calculated.

Shown below is a configuration of the same HD32.3TC instrument with a wet bulb temperature probe. In this case, the wet bulb temperature is directly measured, in compliance to ISO 7243.

HD32.3TC can be configured in various ways for thermal comfort, indoor air quality and microclimate analysis. Please refer to the data sheet of HD32.3TC for more details.
