accurate hygrometer?
 
I've had various thermometer/hygrometer combination devices, but none
of them agree about humidity. Can anyone recommend a brand that is
accurate?

Thanks, Dianna

You do not describe your "device" in any detail. It would be hard to be a
wet bulb/dry bulb psychrometer with appropriate tables to determine
humidity. You still need accurate thermometers. I find that even name brands
such as Taylor are not calibrated well.

By "device", I meant things like the "digital thermo/hybro" as made by
Radio Shack. I've also used the Taylor hygrometers and not been very
impressed. My question is, who makes an accurate one?

I made a spelling error in one of my posts. A sentences should have read:

It would be hard to beat a wet bulb/dry bulb psychrometer with appropriate
tables to determine humidity.

Another approach would be to measure the "dew point." The psychrometer and
dew point measurements will yield absolute humidity. My guess is that all
relative humidity devices such as hair hygrometers are intrinsically
inaccurate.
