The high performance, handheld 
OS-DT8855W infrared thermometer 
is a non-contact temperature 
measurement instrument that 
features a laser circle/dot sight. 
The patented laser sighting system 
defines the target for point and 
shoot measurement of temperatures 
from -50 to 1050°C (-58 to 1922°F) 
and reads surface temperature in 
less than a second.
