if you are looking for small and convenient temp and RH data logger, Voltcraft DL-121TH could be right one. I have it and I am more then satisfied.
small dimensions, light, could be easily hanged any where in GH, has USB connection to pc. software is very good and intuitive. accuracy +/- 3%RH and +/-1C. could measure in C and F.
up to 16000 log records with samle rate from 2sec to 24hours.
logged records could be saved on PC, and exported to Excel format.
the best thing is graphical display of logged data:
with possibility to zoom in/out.
