FLIR T840 Thermal Imaging Camera

Practical Thermal Imaging

The FLIR T840 Thermal Imaging Camera is an extremely sophisticated thermal imaging camera designed to be used by professional thermographers across a range of industries including power distribution and heavy plant production. It has an infrared sensor with a resolution of 464 x 348 pixels and three object temperature measurement ranges: -20˚C to 120˚C, 0˚C to 650˚C, and 300˚C to 1500˚C. Measurements are accurate to ±2˚C or ±2% and excellent thermal sensitivity of 30mK means that temperature differences of just 0.03˚C can be shown on screen.

The FLIR T840 is available with four different lenses: 14˚, 24˚, 42˚ and Dual Field of View (DFOV). Each lens has different fields of view and focus distances. Focusing is done using a laser-guided continuous focus system and it is also possible to get a laser distance reading and use a manual focus system. Automatic area calculation in m2 and ft2 is also available. The 180˚ rotating optical block is particularly useful for observing all around the user during inspections and the imager has an integrated viewfinder.

FlexView Dual FOV 14 - 24˚ Lens

The FlexView Dual FOV 14 - 24˚ Lens is a single lens that offers both 14˚ and 24˚ FOVs, replacing the need to change between two physical camera lenses to achieve each FOV. The FlexiView lens allows for FOV switching with the push of a button and a 1-second FOV toggle time, providing an efficient inspection experience and reducing the physical load for those in the field. This innovative lens retains the sleek design of other FLIR lenses, with an increased length of just 6mm. Performance in both FOVs is retained, offering full radiometric performance and image quality. 

High Quality Thermal Picture

Thermal images are shown on the FLIR T840’s vibrant 4” colour display and a range of palettes are available including iron, greyscale, rainbow, arctic, and lava. A smooth picture in real-time and the saved thermal video is provided by the 30Hz image refresh rate and the high-definition sensor enables 1-6x continuous digital zoom. The imager has various measurement functions such as centre spot, hot spot, cold spot and twin spot surface temperature readings.

An integrated 5MP digital camera takes visual images and video to sit alongside thermal videos and images in the large 8GB SD-card memory. It also enables a wide range of additional display functions on the FLIR T840 such as MSX® image enhancement, picture-in-picture, and thermal blending. One of the standout features of the thermal camera is time lapse which allows the user to monitor an installation over 24 hours to see intermittent faults.

Advanced Analysis Features

The FLIR T840 has multiple analytical features and can store full radiometric thermal video and paired thermal images with visual images. Onboard GPS automatically geotags saved files and it is possible to add 60-second voice observations to video and still images to record observations during inspections. METERLINK® Bluetooth technology allows the camera to combine with FLIR test and measurement equipment to add quantitative data to thermographs whilst USB and Wi-Fi technology allows transfers to PCs or smartphones.

Once files are transferred to a PC, the FLIR T840 is compatible with FLIR Ultramax which can multiply the pixel count by four to vastly increase thermograph clarity. Video streaming is possible over Wi-Fi or a video out cable. The camera is covered by FLIR’s 2-10 warranty with a decade’s guarantee on the sensor. It comes supplied with batteries, a battery charger, a hard transport case, lanyards, a front lens cap, power supplies, an 8GB SD card and USB cables.

Thermal Imaging for Detecting Elevated Body Temperature

This camera includes an EBT screening mode.

While unable to detect a virus or infection, thermal imaging cameras can be used to detect Elevated Body Temperature. FLIR thermal cameras have been used in public spaces—such as airports, train terminals, businesses, factories, and concerts—as an effective tool to measure skin surface temperature and identify individuals with Elevated Body Temperature (EBT).

If the temperature of the skin in key areas (especially the corner of the eye and forehead) is above average temperature, then the individual may be selected for additional screening. Identifying individuals with EBT, who should then be further screened with virus-specific diagnostic tests, can help reduce or dramatically slow the spread of viruses and infections.

Using thermal cameras, officials can be more discrete, efficient, and effective in identifying individuals who need further screening with virus-specific tests. A variety of institutions, including transportation agencies, businesses, factories, and first responders are using thermal screening as an EBT detection method and as part of employee health and screening (EH&S).

Airports in particular are actively employing FLIR thermal cameras as part of their screening measures for passengers and flight crews. The screening procedures implemented at airports and in other public places are just the first step when it comes to detecting a possible infection: it’s a quick way to screen for anyone who might be sick, and must always be followed up with further screening before authorities decide to quarantine a person.
