Wet Bulb Dry Bulb Meter

Fieldpiece meters like the arh5 and the arh4 are staple instruments for every technician tool box.

Wet bulb dry bulb meter. Dry and wet bulb method. The waterless wet bulb meter is a tested and validated alternative to the traditional natural wet bulb sensor. This tool is very easy to use slim and provides instant reading through the screen over the wet bulb rh dew point and dry bulb temperatures. Due to the small 2 inch length probe we classify this one as the entry level model for duct inspection works.

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. The center 317 is a humidity temperature meter with a humidity accuracy of 2 5. Our range of wet bulb dry bulb meters. The meter uses a mathematical model to determine the waterless wet bulb calculation through a combination of dry bulb temperature globe temperature relative humidity and air flow sensors.

Wet dry bulb hygrometer wall mounted thermometers eisco labs. 2 in 1 digital humidity and temperature meter. 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. 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.

List view grid view. 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. Humidity temperature meter dew point and wet bulb ic center317. Traditionally humidity was measured by the dry and the wet bulb method.

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. The dry bulb wet bulb and dew point temperatures are important to determine the state of humid air. 4 0 out of 5 stars 1.

The sensor is protected with a pull up sleeve which protects the unit whilst carrying it around. At lower humidity the wet bulb temperature is lower than dry bulb temperature because of evaporative cooling. At 100 relative humidity the wet bulb temperature is equal to the air temperature dry bulb temperature. Get it as soon as thu sep 24.

Relative humidity and temperature play a large role in creature comfort and commissioning of hvac systems. Ehdis digital psychrometer large lcd thermo hygrometer temperature humidity meter wet bulb dew point measurement temperature humidity meter for indoor outdoor. 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.
