Also, my favorite hygrometer so far is from Big Apple Pet Supply. They have a dual probe version for $25 plus shipping at Amazon http://www.amazon.com/gp/product/B00ADSRFVQ/ref=oh_details_o02_s00_i00?ie=UTF8&psc=1
My caliber iv has been working perfectly. I don't see the need to buy the older version.
Apparently, the Caliber IV was introduced as a response to lower grade copies of Caliber III. I have some Caliber IVs on the way and will be modifying the original post, if they work out as planned. Good luck.

Dried to 59% RH, now I just have to find jars big enough to hold these
Warm air holds more water than cold air.
What's difficult in the tropics is keepin the RH down.

That sounds like a great drying environment for sure. As for curing, it might be tough. There is a LOT of air in that room and when the drying buds run out of extra moisture, depending on the outside RH, the room may start drying out too much to maintain the RH.

Assuming you have good batteries, I'd use a piece of tape with +4 written on it for the outliers.I have 10 caliber 3s and 3 or so give a reading 4% lower then the others
What would you guys do in this case? Just believe the reading that the majority of the meters gives? 68% o 64% is a big difference and I am not sure now if it is at 64 or 68

These instruments give us quantitative numbers to work with but curing is still a subjective thing and based on experience.
+70% RH - too wet, needs to sit outside the jar to dry for 12-24 hours, depending.
