You are bidding on a 1976 9" Model 1328 Taylor Sling Psychrometer. The item has never been used and is in perfect condition. It comes with the original case, instructions, humidity chart and a pack of 6 extra wicks.
The Taylor 1328 Sling Psychrometer is an instrument that measures the wet and dry bulb temperatures of the surrounding air and allows for immediate conversion of these readings to relative humidity percentage. Relative humidity is a ratio of the amount of water vapor in the air to the amount that would be present if the air were saturated. The term "relative" is used because warmer air can hold more water vapor than cold air. Thus, at the same relative humidity, the actual amount of water vapor in the air at, say, 20°F is considerably less than the amount of water vapor in the air at 90°F. Range: 20 to 120 degrees F.
