FAQ
Q
Can the TC004 Lite detect objects underwater, through glass
or a wall?
A
No. Infrared detectors mainly detects 8 to 14 μm long-wave
infrared areas, and can only be used to measure surface
temperature.
Q
Why is there a lower temperature reading when the device
gets far from the object and a higher reading when the
device gets closer to the object?
A
Infrared radiation attenuates when passing through the
atmosphere. The longer the distance, the greater the
attenuation. Thus, the accuracy of temperature measurement at
a distance will decrease.
To ensure accuracy of measurement, go to Setting > Measure
Parameter > Distance, and input the actual distance (max: 5
meters) to get the corrected temperature.
Q
Why is the measured temperature not very precise?
A
The temperature resolution of TC004 Lite is ±2%. And the TC004
Lite provides a normal temperature range of -4 to 302°F (-20 to
150°C), and a high temperature range of 212 to 1,022°F (100 to
550°C). Please select the corresponding range in the Settings
before measuring.
Q
What external factors will affect the infrared temperature
measurement?
A
The following factors will have an impact on the measurement
results:
a) Emissivity of the object surface.
b) Ambient temperature: The object will reflect the infrared
rays emitted by surrounding objects, which affects the
temperature measurement of the object itself.
c) Atmospheric temperature: The atmosphere itself also emits
infrared rays.
d) Atmospheric transmittance: the infrared rays emitted by the
object are attenuated in the atmosphere.
e) Distance: the longer the distance, the greater the attenuation
of the infrared rays emitted by the object in the atmosphere.
