FLIR Heat Gun

Caméra thermique pour évaluer la distribution de la chaleur corporelle.

General Description

The FLIR infrared temperature gun is a handheld device that measures surface temperatures from a distance, without contact, using infrared technology. It is widely used in industrial maintenance, electrical diagnostics, machinery inspection, as well as in the thermal inspection of buildings.

 

Typical Technical Characteristics

FeatureValue
Measurement RangeApproximately −30 °C to +850 °C (depending on the model)
Accuracy± 1 °C or ± 1% of reading (whichever is greater)
Distance-to-Spot Ratio (D:S)Typically 20:1 or 30:1, allowing precise measurement of small targets from a distance
Thermal Sensitivity< 70 mK for certain advanced models
Targeting LaserPresent (Class II) to accurately pinpoint the measurement area
Built-in LED WorklightAvailable on select models for better visibility in low-light environments
DurabilityDrop-resistant (up to 3 m) and sometimes IP-certified for dust and water resistance
EmissivityAdjustable, to accurately measure different types of surfaces (metal, wood, plastic, etc.)
Memory / StorageCapacity to store multiple readings (e.g., up to 99) depending on the model
DisplayLCD or color screen displaying current values, min/max readings, and threshold alarms
Power Supply9V battery or a rechargeable battery pack, depending on the version
Dimensions / WeightHandheld, ergonomic, light to medium weight (designed for one-handed operation)

 

Advantages

  • Fast, non-contact measurement from a safe distance.
  • Highly safe for measuring very hot, hazardous, or hard-to-reach objects.
  • Wide measurement range suitable for both industrial and domestic applications.
  • Practical for electrical diagnostics, detecting thermal leaks, checking machinery, and preventative maintenance.
  • Robust and highly reliable in demanding environments.

 

Limitations

  • Accuracy heavily depends on the emissivity of the surface (shiny or reflective metallic surfaces require special settings or treatments like tape).
  • Measurements can be distorted by distance, target size, steam, dust, or ambient light.
  • Cannot measure the internal temperature of an object, only the visible surface temperature.
  • The sensor lens must be kept clean to guarantee reliable and consistent results.
