Wet bulb dry bulb tool.

Relative humidity and temperature play a large role in creature comfort and commissioning of hvac systems. The sdp2 dual in duct psychrometer is more than just your everyday hvacr psychrometer. Raise dry bulb temp without changing the dew point temp wet bulb temp goes up. The adiabatic evaporation of water from the thermometer bulb and the cooling effect is indicated by a wet bulb temperature lower than the dry bulb temperature in the air.

It has a wide temperature range and an excellent warranty. Lower dry bulb temp without changing the dew point temp wet bulb goes down. It can handle temperature from 40 to 300 f which is outstanding. Wet bulb temperature can be measured by using a thermometer with the bulb wrapped in wet muslin.

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. Wet bulb dry bulb and relative humidity. Supply wet bulb supply dry bulb return wet bulb and return dry bulb. And the warranty is 5 years for the tool and 1 year for the probe.

Snowmaking snow production needs low temperatures and when the humidity decreases the temperature rises. Imo wet bulb in hvac work is more useful when dealing with evaporative cooling concerns such as with cooling towers and swamp coolers. As water evaporates from that wet cloth evaporation cools the thermometer which is identical to how the human body cools itself with sweat. Fieldpiece meters like the arh5 and the arh4 are staple instruments for every technician tool box.

It gives hvacr professionals more insight into hvac evaporator performance than any other psychrometer because it takes four evaporator measurements at one time. This is a great tool. The wet bulb temperature might not be a widely known measure but it has some valuable functions. Construction different materials react differently to different humidities so this temperature is needed when designing a building in different climates.

The wet bulb temperature and the dry bulb temperature will be identical with 100 relative humidity in the air the air is at the saturation line. Meanwhile they both will be the dry and wet bulb thermometers that you could use to measure the relative humidity in a certain area. The natural wet bulb temperature is best described as an old fashioned thermometer wrapped in a wet cloth. On the chart the wet bulb temperature lines slopes a little upward to the left.

The uncovered thermometer measures dry bulb temperature while the one covered with wet cloth measures wet bulb temeprature. Wet bulb temperatures are always lower than dry bulb temperatures with less than 100 relative humidity in the air.
