CAUTION

WARNING
!
Your Kestrel brand Weather & Environmental Meter is designed to
provide accurate measurement of current conditions only. Depending
on your location and environment, conditions may change rapidly.
Rapid temperature and humidity changes (ie moving your meter from indoors to outdoors) may
cause inaccurate readings of temperature and humidity as well as all readings that rely on either of
these values. Before relying on a Kestrel Meter's readings, use care to either a) force air ow over the
sensors by waving or slinging your meter through the air; or b) wait until your unit’s readings have
stabilized, indicating it has equilibrated to its new environment.
To maximize the accuracy and reliability of your readings:
• Ensure that your Kestrel Meter is in good repair and within factory calibration.
• Take readings frequently and carefully according to the guidelines above.
• Allow your meter’s readings to stabilize after signicant changes in temperature or humidity
(ie changing location from indoors to outdoors).
• Allow a margin of safety for changing conditions and reading errors (2-3% of reading is
recommended).
Use extra care and good judgment when referring to your Kestrel Meter to
make any decisions regarding safety, health or property protection.
To reduce the risk of injury or death to persons, read and follow
The Heat Stress, Wind Chill and Thermal Work Limit indices are published indices developed by
the National Weather Service to provide decision guidance based on average human physiological response. Certain individuals, animals, equipment or property may be more susceptible
to harm relating to environmental conditions, requiring additional precautions. For example,
very young or elderly individuals, individuals with asthma or sickling trait, and individuals who
have not become acclimated to hot conditions are likely to be more prone to heat illness, heat
exhaustion, heat stroke or death.
• Know yourself and the individuals and items you are responsible for.
• Where appropriate, seek the guidance of a medical professional.
• Know what to do in the event of heat illness.
• Be prepared with supplies to treat heat illness.
• Have and practice a heat illness action plan.
Your Kestrel Heat Stress Tracker is an environmental meter, not a
medical device. It is only one source of information and must be
employed with care and good judgment.
