Good humidity meter?



Could someone recommend a good meter for monitoring humidity? My latest purchase is apparently way off since it wildly differed from my other 4 in both temperature and humidity. By the way none of the remaining 4 agreed with one another - they varied in temperature by about 3 degrees and humidity by 8 percent. We can at least check temperature with pretty accurate glass thermometers, but humidity?
