Wholesale hand-operated dry wet bulb temperature table

Hand-operated dry wet bulb temperature table models: WD - Six types: temperature and humidity meter structure: manual material: yellow ABS shell body, the blue handle shape dimension: yellow 220 * 45 mm blue handle 84 mm long temperature range: 0 - 50摄氏度 0 - 100% RH: precision & plusmn; 1 c hand-operated dry wet bulb temperature table contains two thermometer, dry thermometer and wet dip thermometer. Two dry foam glass bulb thermometer thermometer exposed to air, shows the air temperature or room temperature; Soaked the glass bulb of the thermometer was wet cloth, because evaporation heat water in wet cloth, so wet thermometer readings than dry dip thermometer readings. And on the same day the air is dry, the faster evaporation, heat, the more the greater the difference of the two thermometer readings; Whereas the more water vapor in the air humidity is bigger, namely the slower evaporation, the smaller the two thermometer readings is poor, so the two thermometer readings can reflect the content of water vapor in the air. Hand-operated dry wet bulb temperature table is measuring the temperature, gas wet a device. Structure: made up of two same ordinary thermometer, one is used to measure the temperature, according to dry bulb thermometer. Another in ball encase with distilled water wet gauze, gauze bottom into distilled water, according to wet bulb. Due to cover the wet bulb gauze after absorbing water evaporation heat absorption, the small in number than the dry bulb thermometer readings. Wet bulb gauze often want to get a new one. When the air is dry, wet bulb gauze to evaporate quickly, absorption of heat, the two thermometer readings difference is big. Two thermometer readings of the greater the difference, the air is dry. When water vapor in the air of a lot of wet bulb gauze evaporation is slow, less heat, the two thermometer readings of the difference is small. The smaller the two thermometer readings is poor, the air is wet. Manual temperature and humidity meter ( Manual temperature and humidity table) Mainly used for high precision demand of humidity and temperature measurement sites!
