The OS-HFV50 Model is a non-contact infrared temperature sensor. The electronics are protected
by a rugged IP64 aluminum alloy(A6061) housing. They calculate the surface temperature based on the
emitted infrared energy of objects and convert the energy into temperature signal.
Infrared thermometer is an optoelectronic sensor. Any object of a temperature above absolute zero (-273 °
C) emits electromagnetic radiation. Infrared thermometer calculates the surface temperature on the basis of
the emitted infrared radiation from the object. By determining its radiation intensity the temperature of an
object can thereby be determined in a non-contact way.

Keep the lens clean at all times. Any foreign matter on the lens would affect measurement accuracy.
Blow off loose particles using clean compressed air. The lens surface can be cleaned with a soft, humid
tissue moistened with water or a water-based glass cleaner. Never use cleaning compounds which contain
solvents for the lens.
Keep away from strong EMF. Avoid static electricity, arc welders, and induction heaters. Avoid abrupt
changes of the ambient temperature. To avoid ground loops, make sure that only one point is earth
grounded.
