Thermal cameras are professional and easy-to-use, and provide fast accurate readings.

They can cover a wide range of surface temperatures with on-screen spot as well as max/min temperature measurement and tracking.

Our cameras also combine a visual and full infrared image on screen, making troubleshooting and pinpointing problems much easier.

Key features to look for when choosing a thermal imaging camera:

How far away are you operating and how small are the objects you are viewing?

• This is important because  it will determine the resolution required in your camera. Specifically you need to be aware of:
  • The Spatial Resolution (IFOV),the smaller the IFOV is, the smaller object and further distance can be measured.
  • Pixel Count, the more pixels, the clearer the image, more temperature points of the thermal image can be measured, smaller targets can be measured and further distances can be observed.
  • Field of View (FOV), essentially determines how much the camera observes at any point in time. Differing lens attachments will allow flexibility here.

Temperature range:

• May seem obvious but it is crucial to check the temperature range, different industries have different requirements so know your application   

Thermal Sensitivity (NETD):

• NETD determines the capability to distinguish between tiny temperature differences. Depending on the characteristics of the targets you are imaging there may naturally be large a large contrast in temperatures ie a hot fuse at 100C+ surrounded by a cabinet at 25C in which case a low NETD is not necessarily needed but if you are looking for small changes in temperature then a lower NETD will be required.

What image do you want to take?

• IR
• Visible
• PIP (Picture in Picture), Thermal overlayed (or blended through) a visible image
• MIF (Multi-spectral Image Fusion), Guide Sensmart patent - supports the fusion of visible image details on the thermal image, which will enhance your observation, experience and work efficiency

Reporting Software:

• Arguably almost as important as choosing the right camera – as a thermographer you are likely to spend as much time in the field as you are creating post surveying reports, hence simple but effective software that makes your job that much easier and efficient is crucial.
