INTRODUCTION
Thank you for purchasing General Tools & Instruments’ SAM800HI or
SAM800IND Digital Pocket Heat Index Monitor. Please read this user’s
manual carefully and thoroughly before using the instrument.
Both models measure ambient temperature and relative humidity (RH)
and calculate the Dew Point and the Heat Index based on those values.
Dew Point can be considered an air saturation temperature associated
with RH. The higher the RH, the closer the Dew Point is to the ambient
temperature. Heat Index is an attempt to quantify how hot a combination
of temperature and RH “feels”.
The only differences between the SAM800HI (Sports model) and the
SAM800IND (Industrial model) are the color of the housing (red vs. black)
and the packaging (illustrated box vs. white box).

audible alarm when the Heat Index exceeds 82°F. To change this
setpoint:
1) With the unit powered off, press and hold the
least 3 seconds. Doing so will cause the display to show the following
terms, all flashing:
2) Press the

OPERATING & MAINTENANCE TIPS
When all display indications flash at once, it’s time to replace the
“CR2032” battery that powers the thermometer (although measurements
will remain valid for several hours after the icon first appears). To replace
the battery, follow the instructions on p. 4.
After subjecting the SAM800HI/SAM800IND to a large change in ambient
temperature, wait at least 30 minutes before making measurements to
guarantee the accuracy of readings.
Remove the battery when storing the unit or when you do not expect to
use it for an extended period of time (months rather than weeks).
Do not disassemble the unit or immerse it in water. Doing so voids the
1-year limited warranty.
