Your cart is empty.The wet-dry bulb thermometer is also a hygrometer, which is simply an instrument used to measure the relative humidity of the atmosphere. It consists of two thermometers, one with a bulb that is kept dry and one that is kept moist. Relative humidity is calculated from the difference in the thermometers' readings as water evaporates from the wet bulb, lowering its temperature. Readings are graduated in Celsius -20° to +50° (in 33.8°F increments) and Fahrenheit 0° to +120° (in 2°F increments). Includes humidity chart in both C and F as well.

All the reviews said theirs was broken when they got it. I took a chance and got it anyway. Well it was broken. I bought the multi pack of fluid thermometers and replaced the broken tubes and it works good
