Related to psychrometer: Sling psychrometer


An instrument that uses the difference in readings between two thermometers, one having a wet bulb and the other having a dry bulb, to measure the moisture content or relative humidity of air.


(Physical Geography) a type of hygrometer consisting of two thermometers, one of which has a dry bulb and the other a bulb that is kept moist and ventilated. The difference between the readings of the thermometers gives an indication of atmospheric humidity. Also called: wet-and-dry-bulb thermometer


(saɪˈkrɒm ɪ tər)

an instrument for determining atmospheric humidity by the reading of two thermometers, the bulb of one being kept moist and ventilated.

Spot checks with a handheld psychrometer in this previous study confirmed that this technique maintained the desired humidity levels (Diederich et al.
This convergence of the two temperatures occurs because the unsaturated air is cooled by the process of continual evaporation, akin to the classic sling psychrometer measurement of wet-bulb temperature.

Under the full sun condition, the meteorological monitoring was performed close to the experimental unit through an automatic weather station (AWS) equipped with a CR 1000 (Campbell Scientific) data acquisition system and composed of the following sensors: global solar radiation (CS300 pyranometer--Campbell Scientific Company), photosynthetically active radiation (PAR Lite--Kipp & Zonen Company) and psychrometer with thermometer shelter (108 Probe Temperature--Campbell Scientific Company) at height of 2.
There were no batteries; just the basics that included a sling psychrometer and a nomograph to calculate relative humidity, a barometer, a wind speed and direction indicator, a rain gauge and others.
Based on equipment, the market is segmented into barometer, anemometer, hygrometer, rain gauge, thermometer, sling psychrometer, and weather balloons.
Ancillary master equipment included imperial and metric altimeters, a psychrometer with an externally mounted sensing head linked via a thermocouple device through a direct current amplifier to a switched display readout meter mounted with the master units; an aircraft heading indicator; an overAerodist communications headset for the master and remote operators to communicate when not in measuring mode; an in-cabin intercom for three-way communications between the master operator, booker and aircraft pilot; and a high frequency radio transceiver to allow radio communications between the booker, remote parties and other field party components (centre party, helicopter support party, etc.
Then sample leave were sealed in a thermocouple psychrometer cup (2 ml) and freezed at 20 C.

The temperature and relative humidity were studio monitors, throughout drying with the aid of a psychrometer.
The temperature was measured using field thermometer while relative humidity was measured with the use of a sling psychrometer.
