[pianotech] Data Loggers

[Tom Rhea, Jr.]

Hi Roger,

 

Thanks for the information.  I think I'm going to pass on the HOBO due to
the fact that the software it needs to interface does not come included with
the instrument.  The $115 price is comparable to some of the others that
I've looked at, but they come with included software.  My budget is limited
at this point so I'm probably going to have to go with the "low-priced
spread" for now.

 

Also, as a former Navy Metrology technician I'm very much aware of how much
drift can occur over time and the need for cross-checking with some sort of
standard or with several comparable instruments.  I've been bitten a couple
of times because of drift.

 

Thanks again.

Tom

Hi Tom,

 

Here at Dampp-Chaser we use the Onset HOBO U12-011.  Onsetcomp.com  We've
used these for about ten years.  We have been able to characterize their
drift over time and don't have to send them back for recalibration since we
know how they perform.

List:

 

Does anyone have a recommendation for a decent Temperature/Humidity
datalogger?  I'm searching for one that will log both T and H every 60
seconds or so - 65K+ data points - with an accuracy of +/- 1 or 2%.  It
should be able to interface with a desktop or laptop computer (XP operating
system).

 

Any suggestions?

 

Thanks,

Tom
