I have used both the ACR SmartReaders and the Veriteq loggers, both
of which I have purchased through Herzog/Wheeler in Saint Paul.  For
general monitoring of exhibit and storage spaces, I prefer the
Veriteq loggers and their requisite software.  Granted I was using
the ACR products a few years ago, so they may have engineered away
some of the bugs I encountered.

The ACR allows for the use of external probes, which the Veriteq
logger does not, so if you're into the whole probe thing, the
Veriteq will not be for you.  The Spectrum software that is packaged
with the Veriteq loggers does some nice data manipulation and is
very easy to export to Excel.  One of the annoying things about the
ACR Trendreader software is that it puts the logger serial number
into the same column as the monitoring data when exported, so you
need to work around that when writing statistical analysis programs.

Another option are the Hobo loggers marketed by Onset corporation.
They cost considerably less (about the cost of an ACR probe!), so
that you can employ many of them at a considerably lower cost than
either the ACR or the Veriteq.  They advertise an RH accuracy of +/-
3%, comparable to the Smartreader Plus line of loggers.
