Introduction
The UT305H infrared thermometer (hereinafter referred to as the thermometer) can quickly
and accurately determine the surface temperature by measuring the infrared energy radiated
from the target surface. It is suitable for non-contact temperature measurement.
Precautions
• To ensure proper use of the thermometer,
• To ensure safety and accuracy of the thermometer,
professional using original replacement
• If the battery symbol on the LCD flashes,
inaccurate measurement.
• Inspect the product case before using the thermometer. Do not use the thermometer if it
appears damaged. Look for cracks or missing
• Avoid keeping the thermometer near high temperature environments for long periods.
• To ensure measurement accuracy, please use the thermometer in the operating environment
[15°C - 30°C, <85% RH (non-condensing)].
• Please use the thermometer indoors where possible.
• The ambient temperature of the measured object must be
measured in places with large airflow such as fans or air conditioning ventilation.
• When changing to a new environment, please leave the thermometer for 30 minutes before
use.
• When the target object is transported from a place where there is a large difference in
temperature from where you intend to take your
vicinity of where you intend to take the temperature measurement for 10 to 30 minutes
to improve accuracy.
• Do not use the thermometer in places with direct sunlight or electromagnetic interference.
• After measuring extremely high or low temperature
for 10 minutes before next use.
• It is recommended to take three measurement of the target object and record the
highest or lowest displayed reading.
• Direct the IR (infrared) sensor lens to face the target object during measurement observing
the optimal measuring distance outlined in the
cause inaccuracies from the actual temperature of the target.
• Infrared Thermometers are not designed to diagnose any medical condition and are
designed to indicate temperature differential between two target objects.
