The Hioki FT3701-20 is a non-contact thermometer using infrared rays, accurately pinpointing the spot with a two-beam laser marker. The infrared temperature gun identifies the surface temperature of an object by measuring the energy level of the infrared rays emitted from the object without physically coming in contact with it.
