HIOKI INFRARED THERMOMETER FT3700, FT3701
Non-contact Infrared Thermometer - Sharply Focus on Measurement Spots with Two-Beam Laser Marker, Ideal for HVAC Applications

The FT3700 and FT3701 are non-contact thermometers using infrared rays, accurately pinpointing the spot with a two-beam laser marker. The infrared temperature guns identify 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.
For industrial use only. Cannot measure body temperature. The laser marker beams are very dangerous if it gets into your eyes.
