General Tools and Instruments HT10 - Manual (Page 3)

INTRODUCTION
Thank you for purchasing General Tools & Instruments’
HT10 USB RH/Temperature Data Logger. Please read this
user’s manual carefully and thoroughly before using the
instrument.
The HT10 is a low-cost, compact, battery-powered thermo-
hygrometer capable of unattended logging (recording) of the
ambient temperature and relative humidity (RH) of an
environment for days, weeks or months. Data logging can
be started or stopped by pushing a button on the unit,
eliminating the need to bring a laptop to the job site.
After a data log has been captured and stored, it can be
uploaded as a .txt file to any PC running the Windows
® 7 or
Windows ® XP operating system after plugging the HT10 into
one of the computer’s USB ports. The HT10’s internal flash
memory is large enough to store up to 8000 pairs of humidity
and temperature readings.
Included with the product—which is slightly larger than a
thumb drive—is a mini-disc with the drivers needed to
interface the unit to the computer, as well as software that
can display a data log file as a table or graph and/or export it
to Microsoft Excel. Exporting to Excel is recommended for
sophisticated trending and analysis of humidity and
temperature data and easy detection of unexpected
excursions.
