HIOKI FT3700 Series Infrared Thermometers

A. Product Overview

The HIOKI FT3700 Series is designed for measuring surface temperature from a safe distance using infrared sensing technology. These thermometers are suitable for applications where direct contact with the measurement surface is difficult, unsafe or impractical.

The FT3700 measures temperatures from minus 60°C to 550°C, while the FT3701 extends the upper measurement range up to 760°C.

The series features laser targeting to help identify the measurement area and includes functions such as maximum, minimum, average and temperature difference measurement.

Key features include:

• Non contact infrared temperature measurement
• FT3700 range from minus 60°C to 550°C
• FT3701 range from minus 60°C to 760°C
• Laser targeting for accurate measurement positioning
• Adjustable emissivity
• Maximum and minimum temperature functions
• Average temperature measurement
• Temperature difference measurement
• Alarm function
• Backlit display
• Continuous measurement capability
• Suitable for industrial and maintenance applications

B. Working Principle

The HIOKI FT3700 Series works by detecting infrared energy naturally emitted from the surface of an object.

Every object with a temperature above absolute zero emits infrared radiation. The thermometer uses an infrared sensor to detect this radiation and convert it into an electrical signal.

The internal electronics calculate the corresponding surface temperature and display the value on the digital screen.

Because the measurement is performed using infrared radiation, the thermometer does not need to physically touch the object.

The laser targeting system helps the operator identify the approximate measurement location. Adjustable emissivity allows the instrument to compensate for different types of surfaces and materials.

C. Why It Is Used

The HIOKI FT3700 Series is used when surface temperatures need to be measured quickly without making physical contact with the object.

This is particularly useful for hot, moving, electrically energized or difficult to reach equipment.

Common applications include:

• Electrical panel temperature inspection
• Motor temperature monitoring
• Bearing temperature checks
• HVAC system inspection
• Machinery maintenance
• Preventive maintenance
• Heating and cooling equipment testing
• Industrial process temperature checks
• Surface temperature comparison
• Troubleshooting overheating components
• Maintenance of rotating machinery
• Temperature inspection of inaccessible surfaces

Non contact measurement can improve measurement speed and allows technicians to inspect equipment without attaching a contact temperature sensor to every measurement point.

D. Suitable Buyers

The HIOKI FT3700 Series Infrared Thermometers are suitable for electrical engineers, maintenance technicians, HVAC professionals, industrial service engineers, plant maintenance teams, electrical contractors, facility management companies, mechanical engineers, manufacturing plants, process industries, quality control departments, field service technicians, automation engineers and companies performing preventive maintenance.

They are particularly suitable for professionals who regularly need to identify overheating equipment or perform quick surface temperature inspections.
