WebThe psychrometer is a combination digital hygrometer and digital thermometer used to measure air temperature, relative humidity, dew point temperature and wet bulb temperature. This portable handheld pocket-sized mini psychrometer allows for the quick and easy determination of indoor ambient environmental conditions. WebThe psychrometer is used to make spot readings, to take readings in areas where there are no hygrothermographs or other monitoring devices, and to calibrate hygrothermographs and hygrom- eters. (See Conserve 0 Gram 312.) There are two types of psychrometers: the sling psychrometer and the aspirating psychrometer.

WebThis Bendix Friez 566-2 psychrometer dates from 1960. It is a simple wet bulb hygrometer where the wet bulb is aspirated by an internal battery-powered electric fan (3 D-cell batteries). Water is applied manually to the wet bulb wick, I use a plastic squeeze bottle with a needle spout. The thermometers range from 10 F to 100 F, though a Celsius ... Webpsychrometer: [noun] a hygrometer consisting essentially of two similar thermometers with the bulb of one being kept wet so that the cooling that results from evaporation makes it register a lower temperature than the dry one and with the difference between the readings constituting a measure of the dryness of the atmosphere. microwave making noise and smoking

WebDesign of Psychrometer. We can say it is a simple hygrometer – which is a device measuring humidity. It has two bulbs both connected with a thermometer. One bulb is wet while the other is dry. We expose the dry bulb to the air so as to measure the temperature. We cover the wet-bulb with a cloth wick and dip it in water until it is ready to use. WebA psychrometer determines humidity by measuring the cooling effect of evaporation. This example has two mercury in glass thermometers, Each mounted a silvered brass plate, and the whole mounted on a wooden board. The plate holding the wet-bulb thermometer is marked "No. 1868 SIGNAL SERVICE U.S. ARMY" and the plate holding the dry-bulb … WebIts roots run deep in the Old South, way back before the American Revolution.
