SHT11 inaccuracy?

I am starting to use an SHT11 that I purchased from parallax, and the convert sensirion object from OBEX, but it seems the output is many degrees F off of what it should be when compared to 2 different laser temp probes, which are very accurate. I cannot attest to its RH accuracy as it is probably the most accurate humidity sensor that I have, but it does seem off... not right. I also checked the math that it does and it seems right out of the manual, the only thing I am not sure of is the resolution that the sensirion object receives for SOrh and and SOt has anyone had any other errors? otherwise tomorrow I will throw it in the fridge, and the heater and check to see what the extremes of the offsets are.
I have also tried other sensors and boards some combinations are closer than others. As it says the RH is not voltage dependant I may just run unadjusted RH levels as I am mostly interested in RH and the extremes of the ambient temp will be 60f to 85f
