Infrared Temperature Meters Sharply Focus on Measurement Spots with Two-Beam Laser Marker, Ideal for HVAC Applications
The FT3700-20 and FT3701-20 are non-contact thermometers using infrared rays. The instruments 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.
