T420 and T440 data sheet - .PDF file.

The Flir T420 thermal camera is helping Zoo osteopath Tony Nevin to diagnose clinical problems in a range of species at Longleat Safari Park effectively and easily.

Nevin has been using thermal-imaging technology for many years to help him diagnose clinical problems in a various species. It allows him to image the whole animal, and the resultant thermal map enables him to make an informed judgement on the condition that is causing the problem and to create an appropriate treatment plan.

Until now, Nevin’s experience with thermal imaging has only been with an old Agema Thermovision 400 series infrared camera; Agema became a Flir company in 1998.

Nevin’s primary objective for using Flir thermal imaging prior to osteopathic intervention is to provide evidence that the condition is likely to respond to treatment. When used in conjunction with other tools, the technology enables Nevin to assess changes in muscle tension state while the animal is at rest. 

Thermal imaging also provides a visual measurement of the overall function of the musculo-skeletal system and a picture of gait symmetry when the patient walks in a straight line.

Key benefits of product application 

  • Nevin wanted to assess the demeanour and movement of Alfie — a highly traumatised elephant with a shoulder problem. To do this, he used a Flir T420 thermal-imaging camera with a 320 x 240 infrared pixel resolution that provides 76,800 individual temperature measurement points in the image. This is important as good thermal sensitivity and image clarity are vital for Nevin’s work.
  • Generally, there is an underlying problem if the temperature difference on the skin surface is greater than 1.5ºC. As the Flir T420 has a thermal sensitivity of less than 0.045°C, it easily meets the need to detect temperature difference of 0.5°C. 
  • The camera is so easy to use Nevin is able to take multiple images for subsequent analysis without the need for manual resetting.
  • The camera’s standard 25º lens generally provides a sufficiently wide field of view to accommodate the whole animal.
  • The low weight of the Flir T420 is of considerable benefit to Nevin. It is discreet so it doesn’t stress the animal and is also easily portable. This is particularly relevant for thermal imaging an animal’s spine to obtain temperature measurements of the dermatome map. 
  • The Flir T420 weighs just 0.88kg, which is suitable for when Nevin has to climb a ladder to image a horse or elephant.
  • Nevin said: ‘I like the tilt screen on the new camera. It’s ideal for applications such as imaging a horse’s thyroid gland. And I can also see an important benefit in being able to take a digital image alongside the thermal one from an identification point of view. It is almost impossible to tell individuals apart from a thermal image.’
  • The Flir T420 is supplied as standard with Flir Tools software but Nevin also uses Flir Tools to help him create more comprehensive thermal-imaging inspection and research reports in Microsoft Word. As a result, professional documents showing anomalies and trends can be easily output in pdf format.

FLIR Systems specialises in technologies that enhance perception and awareness.  The company brings innovative sensing solutions into daily life through its thermal imaging and visible light imaging technology and systems for measurement, diagnosis, location and advanced threat detection.  Its products improve the way people interact with the world around them, enhance productivity, increase energy efficiency and make the workplace safer.

FLIR Systems has six operating segments – surveillance, instruments, OEM and emerging markets, maritime, security and finally, detection. Of these six, ‘instruments’ is of greatest interest to trade and industry and the second largest segment in the company’s portfolio. This division provides devices that image, measure and assess thermal energy, gases and other environmental elements for industrial, commercial and scientific applications.

These products are manufactured across five production sites, three in the USA and two in Europe; Sweden and Estonia.

A model to suit every application and budget
The options that FLIR Systems provides for measuring temperature and studying thermal performance have never been greater.  Not only does the company offer a huge range of models to suit all thermal application needs but the technology is also affordable and very easy to use.  Thermal cameras now come in various shapes, sizes and degrees of sophistication and FLIR continues to invest heavily in the development of new and complementary technologies to differentiate itself from competitors.

An important milestone in the development of thermal imaging has been the introduction of the FLIR Lepton® core, a micro longwave detector, the size of a mobile SIM.  This has allowed thermal imaging to be repackaged to meet the needs of an even wider audience and, in combination with another new technology called Infrared Guided Measurement – IGM™ – has led to the development of a range of test and measurement meters with imaging capability.

Another important growth area for FLIR thermal imaging is in continuous monitoring to assure quality and safety.  Through its introduction of discrete fixed mounted thermal cameras which are fully compliant industry standard plug-and-play protocols, FLIR Systems has provided industry with infrared machine vision which is instantly ready for quick and easy network installation.

Protecting assets and people from fire is an area for which thermal imaging is least known but, thanks to FLIR Systems’ development, it is now one of the most cost-effective methods available.  Its application flexibility and rapid return on investment present an attractive proposition for any site or safety manager.
