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.

How to Use the Hioki Infrared Thermometer FT3700/FT3701
Basic introduction to using a Hioki infrared thermometer Introduces how to use Hioki's FT3700/FT3701 Infrared Thermometer, from activating the laser marker and setting the emissivity to making measurements. The instrument makes it easy to measure the temperature of targets such as an air-conditioner outlet some distance away, a circuit-breaker in a distribution panel that poses the risk if touched, and an operating motor.
Choose according to your measurement location Two Models
FT3700-20: Long-focus, For measuring temperature over a wide area FT3701-20: Long-focus, Precise-field, For measuring temperature at a single point Identify the measurement location reliably Two-point laser marker
Non-contact infrared thermometer featuring simple, one-touch measurement
Easy operation: just pull the measurement trigger Release it to hold the measured value
Since the instrument measures radiation temperature, it’s easy to make readings in hazardous or unreachable locations
Locations that cannot be touched due to moving parts Locations that pose the risk of electric shock Unreachable locations It’s optimal for measuring temperature anywhere
