i really need a hygrometer for my incubator, an old or new will be fine as long as it is accurate.
anyone interested or knowing where to get one please respond.

They usually have hygrometers for auction on egg bay:

Good Luck!

Oh, and in the "search" area type in Hygrometer, I think there are 4 currently for sale from $15.00-$40.00.

Oatman, With my incubator, the hygrometer was just an identical second thermometer, which was fastened at right angles (sideways) to the thermometer, but you attach a wick to the bulb at the base of the one fastened sideways, and the wick extends down into one of the water receptacles and keeps the wick and thermometer bulb wet, so it becomes a hygrometer and registers the humidity. You still need a scale to read it meaningfully. Perhaps someone with incubator instructions can give you the proper reading, which will not be the same as the warm air thermometer. Mine went with the incubator! CJR

Here is the info I found on hygrometers. Give's the conversion on them too.

Humidity is checked by way of a hygrometer, or wet-bulb thermometer in conjunction with a regular "dry-bulb" thermometer. A hygrometer is simply a thermometer with a piece of wick attached to the bulb. The wick hangs in water to keep the bulb wet (hence the name "wet-bulb thermometer"). When you read the temperature on the thermometer and hygrometer, you must then compare it to a chart to translate from wet-bulb/dry-bulb reading to "percentage humidity".
From the relative humidity table, you can see.....
60% humidity reads about 87 degrees on a wet-bulb at 99.5 degrees.
60% humidity reads about 89 degrees on a wet-bulb at 101.5 degrees.
80% humidity reads about 93 degrees on a wet-bulb at 99.5 degrees.
80% humidity reads about 95 degrees on a wet-bulb at 101.5 degrees.
Getting your humidity to become as accurate as your temperature is nearly impossible. It is almost completely impossible with a small incubator. Try to get your humidity as close as you can, and you'll be fine. Just being aware that humidity is important, and trying to get the numbers to come in close will be a huge help to your hatch.
If you can hold within 10-15% things should turn out fine.
