Measuring Relative Humidity (Another Method)
Posted: Thu Dec 20, 2012 1:25 pm
Mario Proulx posted an accurate way to measure relative humidity over on the MIMF. This is simpler and more straight forward than the the drybulb/wet bulb method and all you need is a decently acurate thermometer. I can't describe the procedure any better than Mario so here is a link to his post on the MIMF:

I made up a spreadsheet where you enter the 2 Fairenheit temps and it calculates the realtive humidity so if anyone wants it, here it is:
Also, if you want a decently accurate, competitively priced digital thermometer, here are a couple of suggestions. Both have 0.5C (0.9F) accuracy at room temps. Also digital thermometers are notorius for taking forever to settle on the real temperature but these will go from ambient temp to freezing in 5 or 6 seconds. And bonus, these are great food thermometers! And they are only $19 (even cheaper if you buy 2 or more). These would make great bending thermometers except they only go up to 302F (bummer). I own the first one below.
