Wet bulb is simply a regular thermometer with a "wet sock" on the end so that you read the "wet bulb" temp. It will give you the relative humidity in the incubator without having a hydrometer. There are charts that you can use to look up the numbers.

Here's a link that may be helpful.

I used this method when I wanted to check humidity, and so have never used a hydrometer...
