Properties of air
(OP)
Good day,
I'm looking for a handheld hydrometer that can measure at a temperature of over 220°F, I need to measure specific humidity (lb water/lb dry air) for a drying hood system in a paper mill. Can some one help me with some information?
Thank.

We actually don't work in the 220°F zone, what we do is we use compress air to pull out the hot air out off a exhaust duct that is at 650°F, we control the temp. over 220 so that we don't have condensation, we use a dry bulb thermometer and a wet bulb thermometer, with the help of a psychometric chart we can get the specific humidity.

Thanks for the info, it was very helpful, had a hard time looking for a handheld thermohygrometer that would fit my needs.
