thermography

According to the Office for National Statistics, 66% of adults reported an increase in living costs in January 2022. Of those who reported a rise, 79% cited higher gas and electricity bills as a leading cause. With energy costs rising sharply as a result of the 12% increase in the OFGEM energy price cap in October 2021, it’s no surprise that many households are becoming increasingly interested in making energy cost savings. In addition to these homeowner concerns, environmental considerations are also present amongst much of the population when looking at their energy efficiency, with 22% of UK carbon emissions driven by maintaining a habitable home.

One of the first things that everyone will notice about our thermal imaging cameras and infrared thermometers is that the emissivity capabilities are defined for every single product. Emissivity is either fixed - typically at 0.95 - or adjustable at varying increments between 0.1 and 1 in most thermal imaging cameras. This article aims to explain what emissivity is, how it is determined, and the practical challenges it presents for thermographers and technicians.

Cleaning radiators is an important part of maintaining an efficient, reliable central heating system and power flushing provides a speedy, thorough method of clearing out corrosion and other debris from the system. Part L of the UK Building Regulations even requires that systems are cleaned and flushed before adding anti-corrosion chemicals during commissioning whilst the warranty of new boilers often depends on correct cleaning and flushing. Thermal imaging provides a great, quantitative method of checking the performance of a heating system before and after flushing, thereby confirming the efficacy of the flushing process and visualising the results for the customer.

Four new cameras from Testo are now available from Test-Meter! The Testo 865, 868, 871, and 872 Thermal Imaging Cameras share many useful common features whilst also offering handy additional options and varying thermal imaging specifications across the range. Priced from just £799 to £2199, these cameras offer brilliant value in terms of both image quality and practicality.

Infrared thermography has been used for decades by skilled, trained users in a huge range of applications, from structural surveying of buildings through to electromechanical fault diagnosis, from tracking wild animals to clandestine military activities.

Ask any seasoned thermographer and they’ll regale you with tales of expensive, finicky equipment that had to be treated with kid gloves, was bulky and chomped through batteries. It wasn’t long ago that thermographic cameras had their own specialised on-board cooling systems.

The FLIR E8 Thermal Imaging Camera has been named as a winner of the Red Dot Award: Product Design 2014, one of the most sought-after accolades for quality product design.
