Q&A

what does the sling psychrometer measure

A sling psychrometer can be used to find relative humidity, which is expressed as a percentage. It is computed by multiplying the amount of moisture in the air at a given temperature, dividing by the maxi- mum amount of moisture the air could contain at that same temperature, and then multiplying the quotient by 100.

Does a sling psychrometer measure dew point?

This test method describes how to determine the dew point using a sling psychrometer. A psychrometer measures the ambient air temperature (dry bulb temperature) and the wet bulb temperature. From the dry bulb and wet bulb temperature the dew point is calculated.

What unit of measurement is psychrometer?

A psychrometer is a device for measuring air humidity. It does so by measuring the temperature difference between a dry thermometer bulb and a wet thermometer bulb that has lost some moisture due to evaporation.

Why is a sling psychrometer important?

A sling psychrometer can be used to determine the physical and thermal properties of moist air by using standard tables and charts. Typically it is used to determine relative humidity. Some sling psychrometers include mechanisms to allow relative humidity to be read directly without needing to refer to tables.

What is a sling hydrometer?

Sling Psychrometer, also known as a whirling hygrometer and used fast and accurate humidity readings. The relative humidity range is 1% to 97% RH and has a temperature range of -5—50°C (20—120°F). The handheld device is constructed of a hard plastic unit that protects two encased red-spirit filled thermometers.

What is the use of sling psychrometer and hygrometer?

One of the oldest used instrument for determining relative humidity is the whirling hygrometer (or sling psychrometer). Whirling hygrometer consists of two thermometers that are turned by vigorously swinging the handle and exposing the thermometers to rapid air movement.

What instrument measures dew point?

Dew point can be both measured using a hygrometer, and calculated from a relative humidity value. How do you measure it? Dew point can be directly measured using a dew point hygrometer.

Does a sling psychrometer give you dew point and relative humidity?

The sling psychrometer has two thermometers. The purpose of both is to get both the air temperature, and the ‘wet-bulb’ temperature, which can be used to deduce the dewpoint temp and therefore relative humidity.

Does a psychrometer measure humidity?

Psychrometers. A psychrometer measures humidity by taking both a wet-bulb and a dry-bulb temperature reading. With those two values known, the other properties of the air, including its moisture content, can be determined by computation or by reading a psychrometric chart.

What is the unit of measurement for a psychrometer?

A hygrometer measures the amount of humidity or moisture in the air. The unit of measurement is milliliters per cubic centimeter or the amount of fluid per volume of air.

What is the unit of measurement hygrometer?

Most of the digital psychrometers will display the relative humidity, air temperature, surface temperature, dew point temperature and the difference (spread) between surface temperature and dew point temperature.
