Kung fu maintenance demonstrates how to test indoor wet bulb temperature idwb measure for air conditioners. When air passes over the cloth to evaporate the water the evaporative cooling shows the wet bulb temperature on the thermometer. The wet bulb temperature is the lowest temperature that can be reached under current ambient conditions by the evaporation of water only. But why do we care about this measurement.

The psychrometer does measure relative humidity by utilizing two thermometers called dry bulb and wet bulb. It is instead the temperature read by a special thermometer that is wrapped in water soaked fabric and ventilated. Wet the durable sock and clip to evaporator filters for indoor wet bulb great for finding target evaporator exit temperature. Clip to return vents for indoor wet bulb temperature great for target superheat calculations.

A psychrometer is essentially the type of hygrometer. The atwb1 k type wet bulb thermocouple can clip to hvac r equipment for convenient placement and hands free testing. Temperature of the ordinary air measured by the thermometer when it is covered by wet cloth or wick is called as the wet bulb temperature commonly referred to as wbt.
