Fluke Ti40FT Infrared Camera

Fluke IR-Fusion Technology

Infrared and Visible light images are fused together - enabling you to view images in a range of modes from full IR to full visible light, and see exactly what you are viewing.

See exactly what you are viewing

Fluke IR-Fusion® technology links a real world visual image with a thermal image. It merges the two images into one, with the possibility to blend between the two images or create picture-in-picture combinations. Alarm limits can be superimposed over the visible light image to exactly pinpoint the components exceeding a specified temperature limit. Both the visual images and thermal images are available for use in reports. This speeds up documentation by reducing the need to look for individual images taken with a separate digital camera. IR Fusion helps to better identify and report suspect components and enable the repair to be done right the first time.

Large, sharp thermal images

Thanks to the largest display (five-inch) available on this type of thermal imager in combination with low-noise VOx sensors, the Fluke IR FlexCam units produce exceptionally high-quality images making even the smallest temperature differences visible. This is comparable with images normally only obtained on far more expensive instruments.

A sharp image in every situation

The innovative 180 ° articulating lens makes it possible to view and capture images in areas with poor accessibility. The display remains clearly visible while viewing over high objects, under a machine or around immoveable obstructions. The SmartFocus wheel simplifies getting a stable and sharp image. No need to take your hand off the instrument to turn a focus ring.

Make anomalies visible

Thanks to built-in functions like AutoCapture, the IR FlexCam Thermal Imagers help to troubleshoot difficult problems. The instrument is easily set up to automatically capture only those images where a temperature limit is exceeded. This way, difficult to find intermittent problems can be captured and analyzed quicker by concentrating only on the images containing the anomalies.

Analysis and reporting comes standard

The SmartView™ software (supplied with the unit) includes a complete range of infrared image viewing, analysis, annotation and reporting tools. It even allows for customized reports to accommodate specific company work processes or requirements like multiple image reporting and comparisons.

Radiometric measurement – the ‘data behind the picture’

Fully radiometric thermal imagers capture and store calibrated temperature data for the matrix of thousands of points that make up a thermal image. This makes it possible to perform detailed analysis and change key parameters like emissivity or temperature range either in the field on the camera or in the office using the PC software.

Application samples

Connection of substations

This infrared image shows the "hot" connection (measured using a telescopic lens junction temperature is 225 ° C) in the substation, which feeds power to the hospital and the surrounding her building. Using a thermal imager could immediately fix the defect. The electrical connection has been damaged during a lightning storm, causing the contact to re-welded to the support bracket of the insulator.

Switch 110 A

Switch 240V 110A is used in the LAN system power. The load distribution in phases: A = 65 B = 95 N = 84. Current load for phase B is greater than 80% and the temperature is greater than the nominal value for the switch.


Allocation of excess heat in the distribution transformer was due to the emergence of internal defects and low oil level.


Cold cooling ribs due to low oil level in the transformer.

Transformer radiators

This thermal image shows a cold radiator (bottom left). Perhaps this is due to a faulty pump. Such a situation can be a serious problem, since this reduces transformer efficiency.
