Red Spirit 袖珍干湿计 Red Spirit Pocket Sling Psychrometer

操作简单 - 只需饱和湿温度计的灯芯用干净的水和旋转的悬挂式湿度计直到温度停止下降。在干湿温度刻度计算尺阅读这两个温度计。然后沿箭头将直接指向准确的相对湿度。这一切就是这么简单！随身携带在自己的口袋里。

Simple to operate - just saturate the wick of the wet bulb thermometer with clean water and whirl the Sling Psychrometer until the temperature stops dropping. Read the two thermometers and place wet bulb temperature over the dry bulb temperature scale on the slide rule. The arrow will then point directly to the accurate relative humidity. That's all there is to it! Carry it in your pocket.
