Victor,

We record temp's for our drying ovens, refrigerator, freezer and H20 bath
used for HIER on a daily basis.  Our refrigerator is also on an alarm system
hooked into a computer in plant engineering that is monitored 24 hours/day.
We have been told that we will need to find a way to hook up a temperature
monitoring device that will keep a constant record of our refrigerator and
freezer temps so that we know if there is a problem over weekends or
holidays when the lab is closed.  We do not record our flotation station
(for floating sections) temperature at all.  It has an LED readout but we
adjust the temp not based on what the readout displays but rather how
sections are "behaving" when floated.  Based on that criteria, we feel that
its unnecessary to record the temperature.  We don't process tissue in our
lab, but in previous labs I've worked in, the temps of the procesing
reagents were recorded daily as well.
