HIOKI INFRARED THERMOMETER FT3700, FT3701
U.S.-based sales, and delivery available. The FT3700 and FT3701 are sophisticated non-contact infrared thermometers equipped with a two-beam laser marker for precision targeting. Tailored for industrial applications, they efficiently measure surface temperatures from a safe distance without direct contact, ideal for HVAC systems and hazardous or unreachable areas. Easy to operate by pulling the trigger, they cannot measure body temperature and caution is advised with laser exposure.
Choose from the two models according to your measurement location 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. Accuracy guaranteed: 1 year
