General Tools and Instruments HT50 v.1 - Manual (Page 3)

INTRODUCTION
Thank you for purchasing General Tools & Instruments’
HT50 USB RH/Temperature Data Logger with LCD Display and
IR Thermometer. Please read this user’s manual carefully and
thoroughly before using the instrument.
The HT50 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. It can also measure
and optionally log surface temperatures spot-checked by a
technician using the unit's integral infrared (IR) thermometer.
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 HT50 into
one of the computer’s USB ports. The HT50’s internal flash
memory is large enough to store up to 8000 pairs of humidity
and temperature readings or 5000 sets of humidity, ambient
temperature and surface temperature readings.
Included with the product 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.
