Don't know yet, I just ordered it....for $45 it's worth a try, it takes
measurements every 2 hours (apparently it puts a drain on the
battery), so only done in the background every 2 hrs, done continuesly
when in bar mode. Whats nice is you can check past readings at anytime
to see if its rising/falling. You can download the user manual, check
it out.
Timex has one too I thought but I never found it
I have the Weems & Plath (sp?) combo bar/temp/humidty gauge, but I'm
less than impress with it. When I had it on the boat (in high humidity)
it was
reading temp 15+ degs too high. You can adjust the bar but not the temp
or humidity gauges. Back at home its back to normal.
Another good and inexpensive toy to have is a outdoor/indoor wireless
thermometer,
other than the obvious use, I put the outdoor thermo in the reefer, I
can monitor
temp without opening it up. I just run the reefer when I run the engine
or when
I need to (DC holding plate). Amps are precious on a small boat.
