The whirling hygrometer also known as a sling psychrometer is made out of two thermometers mounted on a frame which rotates around a handle, so it can be whirled in the air by hand. Whirling hygrometer measures dry bulb and wet bulb air temperature. It has numerous commercial uses, but the primary purpose of the device is to measure the amount of water vapor (humidity) in the air.

It has two bulbs both connected with a thermometer.
A psychrometer fitted with a fan is called an aspirated psychrometer or assmann hygrometer.

When the hygrometer is swung in the air, the evaporation… Humidity measurement instruments usually rely on measurements of some other quantities such as temperature, pressure, mass, a mechanical or electrical change in a substance as moisture is absorbed.
Whirling hygrometer is available in either a c or f scale.
Relative humidity is represented as a proportion; Manual operation, no power supply required. Home > environment & climatic testing > dew point testing > whirling hygrometer. A guide for relative humidity (rh) determination is supplied with each instrument and the dewpoint can accurately be calculated using the dewpoint calculator.
It consists of two thermometers mounted in a case with a revolving handle.
Guide for relative humidity(rh) calculation is supplied with each instrument. Or on the work surface, often a guide for relative humidity (rh) calculation is supplied with each instrument. The relative humidity is measured in the air by a hygrometer. Safety precautions for star spray guns.
The dewpoint can be accurately obtained using elcometer 114 dewpoint calculator.
One bulb is wet while the other is dry. Another variant is the sling or whirling hygrometer. Housed in a robust yellow plastic frame and black folding handle, the instrument incorporates a water cistern linked to the wet bulb by means of a cotton sleeve. Thehygrometer is an instrument used for obtaining the relative humidity and dewpoint temperature of the air.
A guide for relative humidity (rh) determination is supplied with each instrument and the dewpoint can accurately be obtained using the elcometer 114 dewpoint calculator.

Itconsists of two identical celsius thermometers, one is called the dry bulb andother the wet bulb.
Star spray gun cleaning & maintenance. The elcometer hygrometers are designed to determine the dewpoint and relative humidity at any given time. One of the oldest used instrument for determining relative humidity is the whirling hygrometer (or sling psychrometer). We will gladly respond to you.
Whirling hygrometer is a device for measuring the relative humidity of air.
When measuring the temperatures, the frame is whirled around like a football rattle. There are many other brands available, including honeywell and ge panametrics. The whirling hygrometer offers the maximum level of accuracy due to the nature of measurement. To determine relative humidity and temperature.
A device that is used to measure the moisture content of the air is called a hygrometer.
We expose the dry bulb to the air so as to measure the temperature. The elcometer 116a whirling hygrometer is available in celsius scale. The whirling hygrometer is available in celsius scale. A hygrometer is an instrument used to measure the amount of water vapor in air, in soil, or in confined spaces.

One of the most economic methods of monitoring relative humidity that utilises the wet and dry principle, thermometers manufactured to bs2842 allows accurate readings to be taken. The whirling hygrometer offers the maximum level of accuracy due to the nature of measurement. There are many physical effects dependent on the amount of water vapor in the air, which have been used to construct whirlin. This hygrometer has a cotton wick covering the top thermometer, and water is wicked from a water reservoir (on the right).
Whirling hygrometer consists of two thermometers that are turned by vigorously.
The whirling hygrometer or sling psychrometer consists of two thermometers mounted on the a frame that can be whirled in the air by hand. Elcometer 116 whirling & sling hygrometer elcometer 116 whirling & sling hygrometer the elcometer 116a whirling hygrometer is available in °c scale. Photo the ceramic sensing membrane from an electronic hygrometer. The drier the ambient (surrounding) air, the more evaporation (and associated cooling) can take place.
It represents the amount of humidity in the air, or vapour, to the maximum amount of humidity that the air can possibly contain.
Both thethermometers are mounted on a single frame and enclosed in a stevenson’sscreen.
