Wet Bulb Dry Bulb Meter

Dry and wet bulb method.

Wet bulb dry bulb meter.

The wet bulb temperature wbt is the temperature read by a thermometer covered in water soaked cloth wet bulb thermometer over which air is passed. Since both the thermometers are placed side by side the mositure from wet wick may affect the readings of dry bulb thermometer to avoid this the wet bulb thermometer is placed at the lower level. 3 6 out of 5 stars 13. Humidity temperature meter dew point and wet bulb ic center317.

The uncovered thermometer measures dry bulb temperature while the one covered with wet cloth measures wet bulb temeprature. Both thermometer readings are taken and the difference between them allows us to calculate the humidity. Relative humidity and temperature play a large role in creature comfort and commissioning of hvac systems. The dry bulb is a common mercury liquid thermometer to measure the air temperature the wet bulb is a second mercury liquid thermometer whose bulb is covered by a muslin bag which is kept moist.

Our range of wet bulb dry bulb meters. The sensor is protected with a pull up sleeve which protects the unit whilst carrying it around.

The knowledge of only two of these values is enough to determine the state of the moist air including the content of water vapor and the sensible and latent energy enthalpy in the air. Accurately measure any environments temperature relative humidity rh dew point wet bulb temperature one step switch between c and f device will power off automatically to save battery when not in use in several minutes adjustable lcd backlight for clearly showing data. At lower humidity the wet bulb temperature is lower than dry bulb temperature because of evaporative cooling. Due to the small 2 inch length probe we classify this one as the entry level model for duct inspection works.
